d1a61703f7 boot/arm-trusted-firmware: licensing info is only valid for v1.4
The licensing information, and especially the name of the license file,
is known only for the official v1.4 version. For example, in later
versions, the license file has been renamed.

Since we can't be sure of the licensing information for custom versions,
or for versions from git, define that only for the known v1.4 version.

69808c7536 package: remove 'v' prefix from github-fetched packages
On Github, a large number of projects name their tag vXYZ (i.e v3.0,
v0.1, etc.). In some packages we do:

 <pkg>_VERSION = v0.3
 <pkg>_SITE = $(call github foo,bar,$(<pkg>_VERSION))

And in some other packages we do:

 <pkg>_VERSION = 0.3
 <pkg>_SITE = $(call github foo,bar,v$(<pkg>_VERSION))

I.e in one case we consider the version to be v0.3, in the other case
we consider 0.3 to be the version.

The problem with v0.3 is that when used in conjunction with
release-monitoring.org, it doesn't work very well, because
release-monitoring.org has the concept of "version prefix" and using
that they drop the "v" prefix for the version.

Therefore, a number of packages in Buildroot have a version that
doesn't match with release-monitoring.org because Buildroot has 'v0.3'
and release-monitoring.org has '0.3'.

Since really the version number of 0.3, is makes sense to update our
packages to drop this 'v'.

This commit only addresses the (common) case of github packages where
the prefix is simply 'v'. Other cases will be handled by separate
commits. Also, there are a few cases that couldn't be handled
mechanically that aren't covered by this commit.

afd6ee3fb1 boot/arm-trusted-firmware: support debug mode
When the trusted firmware is built with debug support (DEBUG defined),
the generated images are located in a different path compared to a
build without debug support. The non debug images are located in
generated directory build/<platform>/release/ while the debug images
are located in generated directory build/<platform>/debug/.

This change introduces the boolean option
BR2_TARGET_ARM_TRUSTED_FIRMWARE_DEBUG to define whether the release or
debug configuration is used to build trusted firmware.

Note that enabling trusted firmware debug support using
BR2_TARGET_ARM_TRUSTED_FIRMWARE_ADDITIONAL_VARIABLES="... DEBUG=1 ..."
would not work since Buildroot will try to copy the generated files
from the wrong path.

6959d628d4 boot/arm-trusted-firmware: add support for using OP-TEE as BL32
This change allows one to build trusted firmware (TF-A) with OP-TEE as
BL32 secure payload.

When BR2_TARGET_ARM_TRUSTED_FIRMWARE_BL32_DEFAULT is enabled TF-A
builds a BL32 stage according the TF-A configuration directive.  If
these specify no BL32 stage then TF-A will build without BL32
support. This is the default configuration and reflects TF-A legacy
integration in BR.

When BR2_TARGET_ARM_TRUSTED_FIRMWARE_BL32_OPTEE is enabled TF-A builds
with support for the OP-TEE OS as BL32.

OP-TEE OS is maintained by the OP-TEE project. It provides an

world as a Linux based OS.

The OP-TEE project maintains other packages to leverage OP-TEE on
Linux kernel based OSes. An OP-TEE interface driver is available
in the Linux kernel since 4.12 upon CONFIG_OPTEE.

This change references in Buildroot the today's latest OP-TEE

9d684a0967 boot/uboot: use HOSTCC_NOCCACHE as kconfig HOSTCC
At kconfig time, dependencies are not built, and therefore host-ccache
is not ready. Due to this, using $(HOSTCC) as the host compiler in
KCONFIG_OPTS does not work: a "make uboot-menuconfig" invocation from
a clean tree with ccache enabled fails.

This commit fixes this by using $(HOSTCC_NOCCACHE). We cannot rely on
the default value of HOSTCC passed by the kconfig-package
infrastructure, because $(UBOOT_MAKE_OPTS) also contains a HOSTCC
definition that would override the one passed by the kconfig-package
infrastructure.

While at it, we move the afboot-stm32 installation into

273a27804a boot/grub2: enable support for arm and aarch64 targets
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.

2d9566b7b7 boot/grub2: add option to install tools
Add an option to install grub2 support tools to the target.

In the context of Buildroot, some useful target tools provided are
grub2-editenv, grub2-reboot, which provide means to manage the grub2,
environment, boot order, and others.

ac0719e086 boot/grub2: separate target and host builds
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.
