1. Make libefi portable by removing ia64 specific code and build
it on i386 and amd64 by default to prevent regressions. These
changes include fixes and improvements over previous code to
establish or improve APIs where none existed or when the amount
of kluging was unacceptably high.
2. Increase the amount of sharing between the efi and ski loaders
to improve maintainability of the loaders and simplify making
changes to the loader-kernel handshaking in the future.
The version of the efi and ski loaders are now both changed to 1.2
as user visible improvements and changes have been made.
changing the Makefile, fail the creation of loader.efi when there are
unresolved symbols in loader.sym. This avoids silently creating a
faulty EFI binary.
binutils 2.15. The linker now creates a .rela.dyn section for
dynamic relocations, while our script created a .rela section.
Likewise, we copied the .rela section to the EFI image, but not
the .rela.dyn section. The fix is to rename .rela to .rela.dyn
in the linker script so that all relocations end up in the same
section again. This we copy into the EFI image.
detects and uses the gas section merge support. As a result, a whole bunch
of new sections arrive, including .rodata.str1.8, which was not included
in our custom ldscript.ia64. The result was a loader binary that EFI
rejected.
While here, collect the loader shell commands linker set and include it
in the data area rather than having its own section.
/boot/loader.efi was the last holdout for having a 100% self built ia64
system.
