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.

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.

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.

case, when U-Boot builds its tools, it requires OpenSSL support on the

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

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.

The SPL generation might work when providing the working

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.
