Dear GRUB folks,
After the GRUB 2.02 release, φ-coder’s work to get GRUB working on ARM
is now in the master branch.
I like to try GRUB with the coreboot “board” *emulation/qemu-armv7
(QEMU ARMv7)*, and did the following under Debian Sid/unstable
```
$ git log --oneline -1
d11ced1e1 arm_coreboot: Support EHCI.
$ ./autogen.sh
[…]
$ ./configure --target=arm --with-platform=coreboot
TARGET_CC=arm-linux-gnueabi-gcc-6 TARGET_OBJCOPY="arm-linux-gnueabi-objcopy"
TARGET_STRIP="arm-linux-gnueabi-strip" TARGET_NM="arm-linux-gnueabi-nm"
TARGET_RANLIB="arm-linux-gnueabi-ranlib"
[…]
$ make -j
[…]
if /usr/bin/makeinfo -I . \
-o grub.info grub.texi; \
then \
rc=0; \
CDPATH="${ZSH_VERSION+.}:" && cd .; \
else \
rc=$?; \
CDPATH="${ZSH_VERSION+.}:" && cd . && \
$restore $backupdir/* `echo "./grub.info" | sed 's|[^/]*$||'`; \
fi; \
rm -rf $backupdir; exit $rc
make[2]: Verzeichnis „/dev/shm/grub/docs“ wird verlassen
Making all in util/bash-completion.d
make[2]: Verzeichnis „/dev/shm/grub/util/bash-completion.d“ wird betreten
../../config.status --file=grub:grub-completion.bash.in
config.status: creating grub

make[1]: Verzeichnis „/dev/shm/grub“ wird verlassen
$ LANG=C make default_payload.elf
make: *** No rule to make target 'default_payload.elf'. Stop.
```
I failed to adapt the command in the Makefile for arm_coreboot.
```
default_payload.elf: grub-mkstandalone grub-mkimage FORCE
test -f $@ && rm $@ || true
pkgdatadir=. ./grub-mkstandalone --grub-mkimage=./grub-mkimage -O
i386-coreboot -o $@ --modules='ahci pata ehci uhci ohci usb_keyboard usbms
part_msdos ext2 fat at_keyboard part_gpt usbserial_usbdebug cbfs'
--install-modules='ls linux search configfile normal cbtime cbls memrw iorw
minicmd lsmmap lspci halt reboot hexdump pcidump regexp setpci lsacpi chain
test serial multiboot cbmemc linux16 gzio echo help syslinuxcfg xnu all_video
$(shell cat grub-core/fs.lst) password_pbkdf2 $(EXTRA_PAYLOAD_MODULES)'
--fonts= --themes= --locales= -d grub-core/
/boot/grub/grub.cfg=$(srcdir)/coreboot.cfg
```
Passing `arm-coreboot` and `arm_coreboot` to the switch `-O` gives back
an error, for example:
```
unknown target format arm_coreboot
```
Could you please tell me how to create the payload file?
Thanks,
Paul
