Arm64 kernels compiled with CONFIG_EFI_ZBOOT=y don't use the ARM64_IMAGE_MAGIC ('ARM\x64') but LINUX_PE_MAGIC (0x818223cd) in the PE Header. Our GRUB fails to boot such a kernel.
We should eliminate the following check:
grub-core/loader/efi/linux.c:75:
if (lh->magic != GRUB_LINUX_ARCH_MAGIC_SIGNATURE)
return grub_error(GRUB_ERR_BAD_OS, "invalid magic number");
This will allow any EFI binary to be run using the linux command. |

[Test plan]
* check that grub and EFI based ARM64 machines boot
* check that MAAS deployment works
[Where problems could occur]
* Non-EFI bootloaders like still want to boot with regular vmlinuz.gz. If one is using piboot, u-boot, abootimg likely one still wants to build Image.gz and have CONFIG_EFI_ZBOOT disabled. |
