c18f65816e
Adds functions to read and write IXP4xx "feature" (aka "fuse") bits, containing information about available/enabled CPU features. The uncompress.h included by boot/compressed/misc.c resides in a different space than rest of the kernel and thus can't use asm/hardware.h (including asm/arch/cpu.h - which, in turn, may use EXPORTed symbol "processor_id").
