Hi,
the following patch adds support for AMD-762. I've tested it on an
uniprocessor system on the Asus Dual Board a7m-266d.
My tests shows that LONG addressing of registers will fail.
Athcool shows the following errors then:
AMD-762 (1022 700c) found
enabling 'Stop Grant Disconnect #0' bit ... failed!
Address 0x60 - 0x67 : (expected) 0x85A30CBD -> (actual) 0xFFFFCEBD
enabling 'Stop Grant Disconnect #1' bit ... failed!
Address 0x68 - 0x6B : (expected) 0x00B38CBD -> (actual) 0xFFFFCEBD
After that disabling or changing the registers is impossible.
When running the same with WORD access, everything works fine. I've also
found the bits to be set for Halt Disconnect in the specification pdfs
from amd (24416.pdf, 24462.pdf, 25818.pdf).
Bye,
Toby
