Thanks Heinrich, so I tested with your approach and u-boot.bin.
The reason why I had no version of arm-efi grub working was
because I had to add --with-platform=efi while
playing "./configure [...]"
On arm64-efi it's fine to forgot it but not in arm-efi builds.
Now I can confirm the same problem and confirm also that the
suggested RFC about grub/include/grub/efi/pe32.h
makes it start on arm-efi (with the u-boot method but also with
various QEMU-EFI-ARM firmwares I recently found).
Unfortunately, the suggested RFC about grub/include/grub/efi/pe32.h
also breaks compatibility with the Asus NovaGo TP370QL I have
here, at least (Qualcomm Snapdragon 835, arm64-efi)
I updated my summary file so anyone can easily drive the arm-efi
tests on future modifications, with a simple x86_64 computer,
qemu, and some minutes of work. https://sorel.pixconfig.fr/GRUB/commands.txt.
Have a nice week end
Julien
PS : may be making a summary of all
architectures/configurations tests tutorials would be useful ?
Even if it's just QEMU (it would even be a lot of work), and
used on new releases or wide changes, or just from time to time
to see if no accident happened in any recent changes. It would
also be an awesome tutorial for people starting to deal with
grub

Hi, I don't know if others folks are
easily able to test and reproduce
the issue and test suggested patch, so I did some builds, and
tests
based on the EFI file produced by grub-mkstandalone using -O

it's a trivial way to test what code version is working or not
with
qemu-system-arm for example.
Unfortunately, with or without applying the RFC suggested
reverting
patch, and even with the Grub 2.02 version, using
qemu-system-arm and an
efi firmware for it, *I can't get any efi version of grub

I did the comparison by building for
* --target=arm-linux-gnueabihf, grub-mkstandalone using -O
arm-efi
(naming the resulting file bootarm.efi)
and
* --target=aarch64-linux-gnu, grub-mkstandalone using -O
arm64-efi
(naming the resulting file bootaa64.efi). I also did make
sure that
I wasn't mixing wrong files during the process.
I placed more details here : https://sorel.pixconfig.fr/GRUB/
(commands
for having everything build and started, qemu EFI firmwares,
resulting
files with current grub and 2.02 of 32 and 64 bits) for those
who
quickly want to do their own tests.
Heinrich, did you succeeded to get an arm-efi version of grub
booting on
some qemu-system-arm machine ? Are you using another qemu arm
efi
firmware ? I'm using this one : https://efi.akeo.ie/QEMU_EFI/
The firmware I am using is U-Boot which is available as
git clone git://git.denx.de/u-boot-efi.git
cd u-boot
make qemu_arm_defconfig
make
To use it with QEMU:
qemu-system-arm -bios u-boot.bin -machine virt -cpu cortex-a15 ...
Also, debian-9.8.0-armhf-netinst.iso and even
debian-10-2019-04-18-JR-armhf-NETINST-1.iso (created using
easy-build
and a local updated mirror), does not seem to contain any EFI
boot
loader (Debian for armhf isn't using efi) so I wasn't able to
confront
any debian armhf efi thing.
You will need a FAT formatted partition mounted at /boot/efi
sudo -s
apt-get install qemu-arm-efi
grub-install --target=arm-efi
update grub
To boot with GRUB you can use these commands on the U-Boot
console:
load mmc 0:2 ${fdt_addr_r} dtb
load mmc 0:1 ${kernel_addr_r} EFI/debian/grubarm.efi
bootefi ${kernel_addr_r} ${fdt_addr_r}
If you want to build the Debian packages yourself on your 32bit
ARM system:
wget
http://deb.debian.org/debian/pool/main/g/grub2/grub2_2.02+dfsg1.orig.tar.xz
wget
http://deb.debian.org/debian/pool/main/g/grub2/grub2_2.02+dfsg1-16.debian.tar.xz
tar -xJf grub2_2.02+dfsg1.orig.tar.xz
tar -xJf grub2_2.02+dfsg1-16.debian.tar.xz
cp -R debian grub-2.02+dfsg1/
cd grub-2.02+dfsg1/
sudo apt-get install \
debhelper patchutils python flex bison po-debconf help2man texinfo
\
gcc-8 xfonts-unifont libfreetype6-dev gettext libdevmapper-dev \
libsdl1.2-dev xorriso cpio parted libfuse-dev ttf-dejavu-core \
liblzma-dev wamerican pkg-config bash-completion
dpgk-buildpackage
cd ..
ls *.deb
You can install the built packages with
sudo dpkg -i \
grub2-common_2.02+dfsg1-16_armhf.deb \
grub-common_2.02+dfsg1-16_armhf.deb \
grub-efi-arm_2.02+dfsg1-16_armhf.deb \
grub-efi-arm-bin_2.02+dfsg1-16_armhf.deb

Finally, I can confirm the qemu efi arm firmware is working at
least
enough for having this efi file running :
https://github.com/pbatard/uefi-simple but it's probably because
the
qemu efi arm firmware comes from here ;) so it's not very
surprising if
it work with it.
If I can help with my time for testing things, feel free to ask
me!
Best regards,
Julien ROBIN

Since this commit a51f953f4ee8

Everywhere or on a specific machines?
I observed the issue on a TinkerBoard (Rockchip RK3288 CPU)
and on
qemu-arm-system -machine virt with the current Debian Buster
GRUB.
