make.base -- renamed OBJECTS to OBJECTS-1 to allow conditional compilation of objects
ldscript.base -- realized that assignemnts to the location counter inside of sections
are relative to their start so simplfied the code
pirq_routing.h -- includeded types.h so we don't have suprises
hardwaremain.c -- unconditionally included arch/smp/mpsec.h
arch/i386/smp/Config introduced conitional on the compilation objects into
the compilation process
ioapic.c -- removed (now) unneeded ifdef around this file
mpsec.c -- removed (now) unneeded ifdef around this file
cpu/cpufixup.h -- Fix typo in the case when no cpufixup is needed.
parts/framebuffer.h -- Added a missing semicolon.
smp/atomic.h -- renamed second atmoic_inc to atomic_dec oops.
tyan/guinnes/Config -- reordered the options so they are grouped a little
better and said mptable.o is dependent on HAVE_MP_TABLE
tyan/guiness/mainboard.c -- small change for clarity.
northsouthbridge/sis/630/northbridge.c
northsouthbridge/sis/630/southbridge.c
-- Remove unused include of the now dead param.h
NLBConfig.py
-- Only include numeric options in the linker script
-- Update to handle adding a condition for when to build
objects
