The arm64 and arm linux kernel EFI-stub support presents pretty much identical interfaces, so the same linux loader source can be used for both architectures. Switch 32-bit ARM UEFI platforms over to the existing EFI-stub aware loader initially developed for arm64. This *WILL* stop non-efistub Linux kernels from booting on arm-efi.
