Subject: [PATCH] xen_boot: add missing grub_arch_efi_linux_load_image_header
|
|
|
|
The new xen_boot module has used grub_arch_efi_linux_load_image_header
|
|
exported by grub-core/loader/arm64/linux.c. It is not a problem for
|
|
upstream but many downstream projects may not use it and take
|
|
grub-core/loader/arm64/efi/linux.c as a replacement as PE entry is the
|
|
preferred way in combination with shim loader.
|
|
|
|
This patch did a trivial workaround just adding back the dropped
|
|
defintion to the xen_boot itself.
