Hi,
the attached patch does the following:
- renames LinuxBIOS to coreboot; in addition you need to mv linuxbios.c
coreboot.c and mv linuxbios_tables.h coreboot_tables.h
- fixes cross compilation with an i386-elf- cross toolchain. i.e. use
$(OBJCOPY) instead of objcopy, add $(CROSS)
- instead of preprocessing bootsect.S into bootsect.s, the intermediate
file is now called bootsect.pre.s. This fixes compilation of memtest86+
on case insensitive filesystems (like NTFS and HFS+)
- Drop unused HWRPB coreboot table type
- Add support for coreboot table forward. The coreboot table may live
somewhere else in memory, in which case there's only a "forwarder" in
the lower 1MB of memory.
Best regards,
Stefan
