[ARM] 4712/2: Adds functions to read and write IXP4xx "feature" bits
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"). Posted to linux-arm-kernel on 2 Dec 2007 and revised. Signed-off-by: Krzysztof Halasa <khc@pm.waw.pl> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
