This commit adds a package for 'shim', an EFI bootloader for secure
boot chain loading.
While gnu-efi supports 32bit ARM, this is currently broken in shim.
Patches to fix this have been submitted upstream but are not included
here for now.

This will be used in packages that depend on gnu-efi, and we take this
opportunity to propagate this dependency where it was missing in
gummiboot and syslinux. In practice, it was not a problem because
gummiboot and syslinux are only available on i386 and x86-64, which is
a subset of the architectures supported by gnu-efi.

Following d0f4f95e39 ("Makefile: rework
main directory creation logic"), BINARIES_DIR is not implicitly
created by the main Makefile at the beginning of the build, leaving
that up to whatever piece of code needs to install something in
$(BINARIES_DIR).
The afboot-stm32 package didn't pay attention to this, which this
commit fixes.
While at it, we move the afboot-stm32 installation into
<pkg>_INSTALL_IMAGES_CMDS, because using <pkg>_INSTALL_TARGET_CMDS to
install only files to BINARIES_DIR is a bit strange.

Add notes to test grub2 running on ARM using qemu. The arm section
describes how to run it using u-boot and aarch64 shows how to do it
using efi, which is similar to what has to be done for x86_64.
The source for OVMF builds is also changed to

This commit enables the arm-uboot, arm-efi and aarch64-efi grub2
platforms in Buildroot.
With the uboot platform, the grub2 image gets built as a u-boot image
and is loaded from u-boot through a regular "bootm". The only
requirement from the u-boot side in order to allow this is that u-boot
is built with CONFIG_API enabled. CONFIG_API seems to not be enabled
by default in most in-tree configurations, however, it seems to be
available for quite some time now. So it might be possible to use this
even on older u-boot versions. This is available only for arm
(32-bit).
With the efi platform, grub2 gets built as an EFI executable. This
allows EFI firmware to find and load it similarly as it can be done
for x86_64. Also, since u-boot v2016.05, u-boot is able to load and
boot an EFI executable, so the uboot efi platform can also be used
from u-boot in recent versions. This has been enabled (mostly) by
default for ARM u-boot. efi platform is available for both arm and
aarch64.

grub2 requires the host grub2-mkimage tool to build some of its target
images. The current way of building this tool in the grub2 package is
to perform a simultaneous host-tools/target-bootloader build during
the grub2 build step.
This method makes the recipe complex to understand, and proved to be a
complication during the work to enable grub2 support for architectures
other than x86.
This patch tries to do a better separation between the build of grub2
host tools and target boot loader image, as a partial step to enable
grub2 to build for other architectures.

U-Boot SPL configures pinmuxes, clocks and other low-level devices. On

By default, the builsystem for uboot defaults to 'legacy', while the
default version is very well capable of using the 'kconfig' buildsystem
instead.
Having the 'legacy' buildsystem be the default in that case makes it
quite inconvenient for users: they would expect to be able to use e.g.
uboot-menuconfig et al. with the default uboot version.
Switch to using 'kconfig' when we use the latest version. Keep the
'legacy' as default for everything else.
Also, invert the 'legacy' and 'kconfig' entries in the choice: it is
nicer to have the recent and future-proof entry first.

Commit baae5156ce (uboot: use local fdt headers) changed the uboot logic
to pass the host include directories with -idirafter instead of -I, so
include files local to u-boot would be preferred over host includes.
This unfortunately breaks configurations using
BR2_TARGET_UBOOT_NEEDS_OPENSSL on hosts with incompatible openssl headers
installed in the system default include directories as explained here:
http://lists.busybox.net/pipermail/buildroot/2018-March/214651.html
The problem is that -idirafter directories gets added to the very end of the
search order, AFTER the system default directories.
Instead use -isystem which causes the directories to be added after -I but
before the system default directories. With this in place, the include
directories of u-boot will first be scanned, followed by the host includes
and finally the system default include directories.

After commit b8c3e94173 ("package/dtc: qemu system build need libfdt")
changed the dtc install target from 'install-bin' to 'install', uboot
compilation failures occurred because libfdt related headers were now
suddenly taken from output/host/include rather than from the uboot sources
itself.
Commit 3a6573ccee ("uboot: use local libfdt.h") solved this by patching
one specific uboot source file, tools/fdtgrep.c, to replace '<...>'-style
includes by '"..."'-style includes.
However, depending on the uboot version, this may not be enough: there may
be other references to fdt header files. In particular taking into account
that it is not uncommon to have vendor-provided uboot trees which have
custom changes.
The root of the problem is that the uboot.mk file passes the host compiler
as follows:
UBOOT_MAKE_OPTS += \
...
HOSTCC="$(HOSTCC) $(HOST_CFLAGS)" \
...
where HOST_CFLAGS contains the string '-I$(HOST_DIR)/include'
The uboot makefiles then use constructs of the form:
$(CC) $(CPPFLAGS) $(CFLAGS) .....
where CPPFLAGS may contain -I references pointing to local directories.
On the expanded compiler command-line, Buildroot's '-I$(HOST_DIR)/include'
is thus present _before_ any -I to local directories, and thus takes
precedence. And that becomes a problem for header files present both
locally as in the Buildroot host directory, which is the case for libfdt.
To fix this problem without having to patch u-boot sources, use '-idirafter'
rather than '-I' to pass the Buildroot host include directory. '-idirafter'
is basically the same thing, but adds the specified directory at the end
of the include precedence chain, rather than at the beginning.

ATF >= 1.3 builds a host program called fiptool which uses
OpenSSL, so we need to build host-openssl. We could have made it an
optional dependency like U-Boot does, but since most ATF versions are
going to be >= 1.3 in the near future, we simply make host-openssl a
mandatory dependency.
However, the ATF build system is not very good, and you can't easily
pass flags that will affect the build of host programs. Therefore, we
take the approach of building fiptool separately before triggering the
real build process.
It would obviously be better to fix ATF itself, but as usual with
those bootloader packages, we fetch different versions depending on
the platform/configuration, making it difficult to use patches.

Since 0542bb79e8 (uboot: Support multiple environment source files),
missing user-supplied environment source files is no longer detected.
This is because we cat them all, and feed the concatenation to the stdin
of mkenvimage. So, if one source file is missing, the cat exits in error,
but the compound command exits with the exit code of the last command,
which is that of mkenvimage, which happens to be happy with whatever it
is fed on its stdin, even is empty.
We fix that by creating a temporary file, that we even leave afterward
for the user to inspect.
We also move it out of the _CMDS block and into a macro of its own, so
that it is easier to write and maintain.

Some platforms (e.g Allwinner ARM64) don't build a FIP image out of
ATF, but only a BL31 image, which is then encapsulated in U-Boot. This
commit adds an ATF option to build such an image.

ATF can be used in different ways:
- ATF encapsulates U-Boot as the BL33, which is what is done on ARM
Juno (currently supported in Buildroot) and Marvell platforms (soon
to be supported)
- U-Boot encapsulates ATF's BL31, which is what is done on Allwinner
ARM64 platforms.
Until now we were assumming the former was always the case, but
obviously it isn't. Therefore, this patch adds an option that allows
to explicitly tell ATF that it encapsulates U-Boot as its BL33.
We adapt the only defconfig that uses ATF so that it enables this
option as appropriate.

Currently, our arm-trusted-firmware unconditionally builds a FIP
(Firmware Image Package). While this is often needed on platforms
where ATF encapsulates U-Boot, it is not the case on some other
platforms where it's U-Boot that encapsulates parts of ATF.
In order to prepare the support for the later platforms, we make
building the FIP image optional, and update the only defconfig we have
that uses ARM Trusted Firmware.
Note: we considered adding a "default y" here to preserve backward
compatibility, but there really isn't any default that is sane:
whether a FIP image needs to be built or not is purely platform
specific.

grub is no longer maintained: it is stuck at version 0.97 with huge
patches that have no opportunity to be applied upstream, as upstream
has even renamed it grub-legacy.
Besides, it no longer builds correctly with recent binutils versions,
and even the huge patches we could grab from Debian do not help the
slightest.
Since upstream really considers it dead, and there are at least two
alternatives (grub2 and syslinux), just remove grub.

After many years since the last release and a long time with grub 2.02
in beta, there is finally a release and it brings many bug fixes and
interesting features such as support for ARM.
Patch boot/grub2/0001-remove-gets.patch doesn't seem to be required
anymore as grub-core/gnulib/stdio.in.h has changed significantly since
"053cfcd Import new gnulib." and has another treatment for gets.

So let's add an option in the U-Boot package to generate such a boot

Note that we assume a single script needs to be generated, and the
output file name is boot.scr. The only platform for which it seems to
not be the case are the Boundary Devices platforms: they generate two

Instead of excluding the hash specifically for the custom tarball and

This simplifies the code a little because soon we will add hash checks
for git as well, so we also need an exclusion in that case.
It is not needed to exclude it twice for barebox and barebox-aux,
because they use the same source tarball and barebox-aux can only be
enabled if barebox is enabled. So simplify even further by pulling

Until now, the host toolchain was used to build syslinux, as it was
not possible to build a 32-bit syslinux with a x86-64 toolchain.
However, syslinux requires gnu-efi, and gnu-efi is built using the
target toolchain. Mixing different toolchains doesn't work well, so
this commit changes the syslinux package to use the target toolchain
for syslinux as well. This is made possible by patches
0003-Fix-ldlinux.elf-Not-enough-room-for-program-headers-.patch and
0004-memdisk-Force-ld-output-format-to-32-bits.patch.
Since syslinux also contains some utilities that have to run on the
host, those have to continue being built with the host toolchain,
which requires patch 0005-utils-Use-the-host-toolchain-to-build.patch.
Patch 0006-lzo-Use-the-host-toolchain-for-prepcore.patch is about
building prepcore, another utility with the host toolchain as it is
required at build-time.
This was tested using a Buildroot's built x86_64 toolchain, and
checked that the output binaries are 32-bits. It was tested as well if
they actually boot on hardware.

On older SoCFPGA SoCs, there was not enough SRAM to fit the entire
U-Boot, so a SPL model was used. The SPL was therefore the binary that
had to be "prepared" to be loaded by the ROM code using the mkpimage
tool.
With newer SoCFPGA SoCs, there is enough SRAM to fit the entire U-Boot,
and therefore the ROM code directly loads U-Boot. In this case, it's the
real U-Boot image (not the SPL) that needs to be prepared using
mkpimage.
This code adds support for the newer SoCFPGA SoCs, by adjusting the
mkpimage related logic to apply on the SPL if an SPL is enabled, or on
the full U-Boot image otherwise.

Commit 3e3fef39e7 added new and improved
patch handling, with BR2_TARGET_UBOOT_PATCH. This was in addition to
the existing BR2_TARGET_UBOOT_CUSTOM_PATCH_DIR option, that only
handled directories.
Later, commit 21b25d28fc moved the old
BR2_TARGET_UBOOT_CUSTOM_PATCH_DIR to legacy options. But on the way,
bad things happened:
* The original option was a string, while the one added to Config.in.legacy
is a bool. This results in a warning from defconfigs that actually define
the old BR2_TARGET_UBOOT_CUSTOM_PATCH_DIR (because a string is not a valid
value for a bool), but it does not result in the legacy option being
selected. Consequently, BR2_LEGACY is not selected either.
* The advice at the top of Config.in.legacy to add a hidden WRAP option
to select BR2_LEGACY was not heeded.
* The advice at the top of Config.in.legacy to use the old string
option as the default for the new string option was not heeded. In
this case, the variable was not just renamed, as the old option
supported directories only, while the new one supports files too.
But since the old option is a subset of the new option, it can still
be used to set a useful default.
So, this mod turns the legacy option back to a string, adds a hidden
bool WRAP option to set BR2_LEGACY when the string is non emoty, and
uses the legacy option to set the default for the new option.

Some U-Boot board configurations have CONFIG_FIT_SIGNATURE=y. In this
case, when U-Boot builds its tools, it requires OpenSSL support on the
host system.
Since we clearly don't want to unconditionally depend on host-openssl,
we introduce a new option to explicitly enable the dependency on
host-openssl. This is exactly identical to the existing
BR2_TARGET_UBOOT_NEEDS_DTC, for the dependency on host-dtc. It is
therefore the responsibility of the user to enable this option if his
board configuration uses CONFIG_FIT_SIGNATURE=y.
Necessary to fix bug #9316.

This unique NAME is used to construct a per br2-external tree variable,
BR2_EXTERNAL_$(NAME)_PATH, which contains the path to the br2-external
tree.
This variable is available both from Kconfig (set in the Kconfig
snippet) and from the .mk files.
Also, display the NAME and its path as a comment in the menuconfig.
This will ultimately allow us to support multiple br2-external trees at
once, with that NAME (and thus BR2_EXTERNAL_$(NAME)) uniquely defining
which br2-external tree is being used.
The obvious outcome is that BR2_EXTERNAL should now no longer be used to
refer to the files in the br2-external tree; that location is now known
from the BR2_EXTERNAL_$(NAME)_PATH variable instead. This means we no
longer need to expose, and must stop from from exposing BR2_EXTERNAL as
a Kconfig variable.
Finally, this also fixes a latent bug in the pkg-generic infra, where we
would so far always refer to BR2_EXTERNAL (even if not set) to filter
the names of packages (to decide whether they are a bootloader, a
toolchain or a simple package).
Note: since the variables in the Makefile and in Kconfig are named the
same, the one we computed early on in the Makefile will be overridden by
the one in .config when we have it. Thus, even though they are set to
the same raw value, the one from .config is quoted and, being included
later in the Makefile, will take precedence, so we just re-include the
generated Makefile fragment a third time before includeing the
br2-external's Makefiles. That's unfortunate, but there is no easy way
around that as we do want the two variables to be named the same in
Makefile and Kconfig (and we can't ask the user to un-quote that variable
himself either), hence this little dirty triple-inclusion trick.

happened right after v2016.09 was released an so we need to have that fix
for v2016.07 which is mentioned in axs10x defconfigs and for the latest
U-Boot release v2016.09 (which is selected by default if no defconfig is
used).
Once we deprecate either U-Boot version in U-Boot corresponding patch

Since commit 0dca644e44 ("boot/uboot: fix
missing host-openssl for i.MX28 target"), we pass HOSTCFLAGS/HOSTLDFLAGS
in the environment of U-Boot when building. This is needed to allow
U-Boot to find the OpenSSL headers/libraries when they are
needed. Unfortunately, this breaks the build with old U-Boot versions as
the U-Boot Makefiles were not designed to have HOSTCFLAGS passed in,
which causes some important CFLAGS from the U-Boot build system to be
ignored.
As suggested by Arnout, we pass the HOST_CFLAGS inside HOSTCC directly,
which allows to pass the CFLAGS without overriding the internal U-Boot
CFLAGS.
Tested with an old U-Boot (2012.10), and a modern U-Boot in a
configuration that needs OpenSSL.

Add the required dependency 'host-openssl' to all the different U-Boot image
types used to build a bootloader image for an i.MX23/i.MX28 target.
Also pass HOST_CFLAGS and HOST_LDFLAGS to the U-Boot build process so the right

passed to the uboot build. This causes a compilation issue as uboot
uses the top-level system architecture as it's $(ARCH). So
arch/$(ARCH)/Makefile doesn't work with arm64 unless we adjust the
arch.

Some U-Boot configurations require the Device Tree compiler to be
available, so we need to depend on host-dtc (example configuration:
zynq_zed).
However, we don't want to build it unconditionally, since the vast
majority of U-Boot configurations don't need it (and host-dtc itself
has a bunch of dependencies).
So, we simply add a Config.in option that allows users to indicate
whether their U-Boot needs DTC or not, and depend on host-dtc if this
option is enabled.

Fixes https://bugs.busybox.net/show_bug.cgi?id=8256
grub2's build system interprets CC, CFLAGS and CPPFLAGS as for the host
and uses TARGET_CC etc. for the target. However, NM, OBJCOPY and STRIP
are used for the target. We currently pass the host-versions of these
tools as part of $(HOST_CONFIGURE_OPTS).
While we're at it, also pass TARGET_LDFLAGS.
This problem had not been noticed up to now because usually we build on
an x86 machine for the x86 architecture, so the binutils are compatible.
However, this is not true on an i386 when building for x86_64.

Note there's a probability that this particular patch won't make its way

we need to fix U-Boot building in Buildroot anyways.

With the patchset "kconfig: turnaround into single .config"
[http://lists.denx.de/pipermail/u-boot/2015-February/205490.html]
U-Boot switched to a single .config file for board configuration. This
allows us to use the kconfig-package infrastructure.

This commit integrates generation of a bootable image
for Xilinx Zynq. The generation is independent on Xilinx
flow and utilizes the host-zynq-boot-bin package. The only
required step is to generate a proper U-Boot SPL (instead
of the FSBL).
The SPL generation might work when providing the working
ps7_init.c file to U-Boot. However, from U-Boot 2015.07
a set of generic ps7_init.c files is included and used to
build the U-Boot SPL for various boards. The ps7_init.c file
has been released under GNU/GPL license for this purpose.
For details, see
http://lists.denx.de/pipermail/u-boot/2015-April/210664.html

Allow to generate 'u-boot.nand', Freescale i.MX28 BootStream format (.sb)
with a header for booting from NAND flash.
There are two possibilities when preparing an image writable to NAND flash:
1) The NAND was not written at all yet or the BCB (Boot Control Blocks) is
broken. In this case, the NAND image 'u-boot.nand' needs to written.
2) The NAND flash was already written with a good BCB. This applies after
'u-boot.nand' was correctly written. There is no need to write the BCB
again. In this case, the bootloader can be upgraded by writing 'u-boot.sb'.
To satisfy both cases 'u-boot.nand' as well as the make target 'u-boot.sb' are
copied to the binaries directory.
mxsboot for NAND images needs all three parameters typed in as integer values
(hex values do not work). The default values choosen are typical sizes for a
NAND flash.

In order to support ISO9660 bootable images that rely on Grub 2, this
commit modifies thr Grub 2 makefile to generate and install an El
Torito image. Such an image is simply produced by concatenating the
cdboot.img provided by Grub 2, and the Grub 2 image generated by
Buildroot using grub-mkimage.
Since this action is so simple and cost-free, we don't bother adding a
Grub 2 sub-option for that, and simply generate the El Torito image
unconditionally.

For custom tarballs, it's quite obvious we can not check hashes.
For custom versions, that's not so obvious. One might think we could
have hashes for all the official releases, but that's not possible: if
the user uses a released version of Buildroot (say 2015.05) much later
in the future, and wants to use the then-released 2038.02 U-Boot. It now
seems pretty obvious that Buildroot 2015.02 can't know the hash for
U-Boot 2038.02.
So, disable checking the hash for custom tarballs and custom versions.

In at91bootstrap3, defconfig files are spread out in various
sub-directories, so we can't easily construct the path to those
defconfig files.
As it turns out, there are no two defconfig files named the same; they
all contain at least the board name, plus some extra info. And there is
always only one directory depth below board/ where all defconfig files
are to be found.
Also, at91bootstrap3's own Makefile relies on this single-match as it
runs a 'find' command to locate the defconfig file.
So, even though we do not know the path to the defconfig file, we can
construct a shell-glob quite easily (in the hope that there will never
be more than one directory depth).

Several packages have some logic to apply custom patches that existed
before the BR2_GLOBAL_PATCH_DIR mechanism: at91bootstrap,
at91bootstrap3, barebox, uboot and linux. Currently, the logic of
those packages to apply custom patches is to match
<package-name>-*.patch, which is not consistent with what we've done
for patches stored in the package directory, and for patches stored in
BR2_GLOBAL_PATCH_DIR: in such cases, we simply apply *.patch.
