[U-Boot] efi_loader: handling of global data in *.efi files

[Heinrich Schuchardt]

Hello Alex, hello Simon,

in arch/arm/lib/elf_aarch64_efi.lds we merge the .bss section into the
.data section with a comment by Simon:

"The EFI loader doesn't seem to like a .bss section, so we stick it into
.data".

Real live EFI binaries like iPXE's snp.efi have a .bss section:

Number of Sections 6
Section[0] .text
Section[1] .rodata
Section[2] .data
Section[3] .bss
Section[4] .reloc
Section[5] .debug

Do you remember what the exact problem was with .bss sections?

.bss sections have to be initialized after relocation. I could not find
any code relating to this in efi_image_loader.c. Did I miss it?

Best regards

Heinrich
