The CPU and firmware feature fixup macros are currently spread across three files, firmware.h, cputable.h and asm-compat.h. Consolidate them into their own file, feature-fixups.h Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Acked-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
