- move src/arch/i386/smp/ioapic.c to src/arch/i386/lib/ioapic.c (has
nothing to do with SMP) - move src/arch/i386/smp/mpspec.c to src/arch/i386/boot/mpspec.c (where acpi, pirq and coreboot table generation lives) - modify src/arch/i386/boot/Makefile.inc, src/arch/i386/lib/Makefile.inc and src/arch/i386/smp/Makefile.inc accordingly - src/arch/i386/smp is now empty. drop it. - drop src/arch/i386/init/car.S (unused) Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Patrick Georgi <patrick.georgi@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5460 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
