From: Sylvain Gault <sylvain.gault at gmail.com> These few patches contain a few improvement about the Makefiles for EFI. Mainly, to rebuild the files when needed, and only when needed. The three shell scripts efi/{check,build,clean}-gnu-efi.sh disappeared and are now integrated as makefile recipes. You'll notice an argument ARFLAGS=rvU to the recursive make calls to gnu-efi. This is

This patch adds to the core EFI image booting capabilities. It was tested on VMware EFI clients and HP Elitebook EFI notebooks, only on PXE environments but it should work on non-PXE scenarios as well. Feedback appreciated.

Hi Ady, Would it work if we removed "ifdef EFI_BUILD" condition and just add -mno-red-zone for all x86_64 builds? If not, do you have any ideas how to pass this flag? This could work, because the patch is adding the -mno-red-zone flag only for x86_64 builds, which are only used in the form of the efi64 target. The efi32 and bios targets are both 32-bit. BTW. I also tried 6.04-pre1 and
