Message:

new boot infrastructure

• more code and metadata unification
• import of up-to-date implementations from the kernel
• the boot loaders should behave more similarly on all platforms
• support for deflate compressed (LZ77) boot components
  • this again allows feasible boot images to be created on mips32
• IA64 is still not booting
  • the broken forked GNU EFI library has been removed, a replacement of the functionality is on its way

File:

• boot/genarch/include/division.h (moved) (moved from boot/arch/arm32/loader/print/print.c ) (2 diffs)

boot/genarch/include/division.h
