[coreboot] problem about ioapic

[aaron lwe]

hello,

I'm trying to make vt8237r ioapic work, but kernel cannot boot.

Kernel seems to have problems about 8254 timer:
ENABLING IO-APIC IRQs
..TIMER: vector=0x31 apic1=0 pin1=2 apic2=0 pin2=0
..MP-BIOS bug: 8254 timer not connected to IO-APIC
...trying to set up timer (IRQ0) through the 8259A ...
..... (found pin 0) ... failed.
...trying to set up timer as Virtual Wire IRQ... works.
Using local APIC timer interrupts.

And kernel hangs at:

I've created floating table in mptable.c and tried both factory bios
config table and the one created by mptable in util directory.
same result. the kernel parameter I passed is acpi=off apic=debug.
local apic should be setup in lapic.c, this is a c7 cpu and
CONFIG_IOAPIC is set to1.

so what's left to be setup? thanks.
