Subject: [PATCH 2/3] Make loongarch64 use efi-app-loongarch64
|
||||||
|
|
||||||
|
Binutils 2.41 now supports efi-app-loongarch64, so to use this we must add a
|
||||||
|
dummy reloc section and remove the PE header definition from crt0 as this will
|
||||||
|
conflict with the version added by objcopy
