[v2,0/2] ARM: compressed: reorganize section layout and enable EFI debugging

Message

Ard Biesheuvel Nov. 5, 2018, 7:43 p.m. UTC

Tweak the output section layout of the decompressor so that the ELF and
PE/COFF .text sections start at the same offset in the image. This is
a prerequisite for enabling a EFI debug header that is highly useful
when debugging the interactions of the EFI stub code with the firmware.

v2:
- drop changes to the .start and .text sections: those changes were based
  on a misinterpretation on my part of the documented behavior of ld.bfd
  when it comes   to ordering input sections.

  ARM: compressed: put zImage header and EFI header in dedicated section
  ARM: efi: add PE/COFF debug table to EFI header
