[coreboot] AMD platform: IO-APIC => Local APIC delivery modes

[Rudolf Marek]

Hi again

>> You can perhaps generate NMI using MSI/MSI-X or HPET (i tried with this)

I did the HPET NMI generator on Intel PCH, it works fine. I just fill the MSI
addr/data in a way that it was delivering NMI to certain CPU - physical delivery
to a CPU with a certain ID.

If this does not work on AMD, perhaps there is some problem with chipset
configuration. Please check the HT specs and try to sort out the MT3 setup.

Thanks
Rudolf
