grub2: bump up version 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. Patch boot/grub2/0002-grub-core-gettext-gettext.c-main_context-secondary_c.patch was a backport which is present after the bump and therefore is also no longer necessary. Since we're adding a Config.in comment, we also introduce a BR2_TARGET_GRUB2_ARCH_SUPPORTS hidden boolean, in order to avoid repeating the architecture dependencies. Signed-off-by: Erico Nunes <nunes.erico@gmail.com> Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> [Thomas: add BR2_TARGET_GRUB2_ARCH_SUPPORTS, remove bogus dependencies on ARM and AArch64, since enabling Grub2 on those architectures is done in another commit.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

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.

boot/grub2: add support to build multiple Grub2 configurations in the same build When Grub2 is build it is configured only for one boot set-up, BIOS Legacy, EFI 32 bit or EFI 64 bit. It can not deal with several boot set-up on the same image. This patch allows to build Grub2 for different configurations simultaneously. To cover Grub2 configuration of legacy BIOS platforms (32-bit), 32-bit EFI BIOS and 64-bit EFI BIOS in the same build, multi-build system felt much more reasonable to just extend the grub2 package into 3 packages. We can no longer use autotools-package as a consequence of this multi-build, and we have to resort to generic-package and a partial duplication of the autotools-infra. Grub2 was already using custom option like --prefix or --exec-prefix so this won't add much more weirdness. We use a GRUB2_TUPLES list to describe all the configurations selected. For each boot case described in the GRUB2_TUPLES list, it configures and builds Grub2 in a separate folder named build-$(tuple). We use a foreach loop to make actions on each tuple selected. We have to separate the BR2_TARGET_GRUB2_BUILTIN_MODULES and the BR2_TARGET_GRUB2_BUILTIN_CONFIG for each BIOS or EFI boot cases.

GNU GRUB is a Multiboot boot loader. It was derived from
GRUB, the GRand Unified Bootloader, which was originally
designed and implemented by Erich Stefan Boleyn. GRUB 2 has
replaced what was formerly known as GRUB (i.e. version
0.9x), which has, in turn, become GRUB Legacy.
Amongst others, GRUB2 offers EFI support, which GRUB Legacy
doesn't provide.

The file boot/grub2/grub.cfg is used by default as the Grub
configuration file. It can be overridden using a rootfs
overlay or post-build script.
grub2: move usage notes to package readme.txt As discussed in the mailing list, grub2 usage notes were growing too big for a Config.in documentation, and so it was agreed that a readme.txt in the package directory is a better place to put them. This commit simply moves the documentation as-is to preserve the original contents as they were in Config.in which can be worked on in further commits.

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.

It can not deal with several boot set-up on the same image. This patch allows to build Grub2 for different configurations simultaneously. To cover Grub2 configuration of legacy BIOS platforms (32-bit), 32-bit EFI BIOS and 64-bit EFI BIOS in the same build, multi-build system felt much more reasonable to just extend the grub2 package into 3 packages. We can no longer use autotools-package as a consequence of this multi-build, and we have to resort to generic-package and a partial duplication of the autotools-infra. Grub2 was already using custom option like --prefix or --exec-prefix so this won't add much more weirdness. We use a GRUB2_TUPLES list to describe all the configurations selected.

boot/grub2/Config.in: add symbols to represent legacy and EFI boot There are cases to want a synthetic information whether the legacy BIOS or U-Boot boot scheme, or the EFI boot scheme, are enabled, without resorting to testing all and each platforms. This is already the cae in grub2 itself, for the configuration of the BIOS/U-Boot boot partition, and builtin modules and configuration on one hand, and the EFI builtin modules and configuraiton on the other hand. It is also the case for mender-grubenv, which will want to know if either or both are enabled, but without having to resort to testing all the cases. Add two new symbols, that each represent those conditions: * BR2_TARGET_GRUB2_HAS_LEGACY_BOOT * BR2_TARGET_GRUB2_HAS_EFI_BOOT Each target selects the appropriate bool, which makes it much more simple for other packages such as mender-grubenv to check if grub legacy or EFI is selected. And of course, we also make use of those symbols in grub2 itself, to simplify the conditions for showing.hiding legacy and EFI options. Additionally (but that does not merit being in its own patch), add a comment on the closing 'endif' for the EFI part.

boot/grub2: add support to build multiple Grub2 configurations in the same build When Grub2 is build it is configured only for one boot set-up, BIOS Legacy, EFI 32 bit or EFI 64 bit. It can not deal with several boot set-up on the same image. This patch allows to build Grub2 for different configurations simultaneously. To cover Grub2 configuration of legacy BIOS platforms (32-bit), 32-bit EFI BIOS and 64-bit EFI BIOS in the same build, multi-build system felt much more reasonable to just extend the grub2 package into 3 packages. We can no longer use autotools-package as a consequence of this multi-build, and we have to resort to generic-package and a partial duplication of the autotools-infra. Grub2 was already using custom option like --prefix or --exec-prefix so this won't add much more weirdness. We use a GRUB2_TUPLES list to describe all the configurations selected.

grub2: bump up version 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. Patch boot/grub2/0002-grub-core-gettext-gettext.c-main_context-secondary_c.patch was a backport which is present after the bump and therefore is also no longer necessary. Since we're adding a Config.in comment, we also introduce a BR2_TARGET_GRUB2_ARCH_SUPPORTS hidden boolean, in order to avoid repeating the architecture dependencies.
