Hi Dan Williams:
I found the IOP80331 pci outband windows it not correct, the outboand
window size is 128Mbyte, split with two 64MByte window, the first outband
translate address is 0x80000000, so the second translate address must
0x84000000, but in linux kernel it is 0x88000000.
I try to enable the direct windows outband window in iop80331 but not
work, can you give me some point.
thanks.
