[ 0.097651] node 0 link 0: io port [b000, ffff]
[ 0.097654] TOM: 0000000040000000 aka 1024M
[ 0.097657] Fam 10h mmconf [e0000000, e00fffff]
[ 0.097659] node 0 link 0: mmio [a0000, bffff]

[ 0.097663] node 0 link 0: mmio [f0000000, fe02ffff]
[ 0.097665] node 0 link 0: mmio [e0000000, e04fffff] ==> [e0100000, e04fffff]
[ 0.097668] bus: [00, 04] on node 0 link 0
[ 0.097670] bus: 00 index 0 [io 0x0000-0xffff]
[ 0.097672] bus: 00 index 1 [mem 0x000a0000-0x000bffff]
[ 0.097674] bus: 00 index 2 [mem 0x40000000-0xdfffffff]
[ 0.097676] bus: 00 index 3 [mem 0xe0500000-0xffffffff]
[ 0.097677] bus: 00 index 4 [mem 0xe0100000-0xe04fffff]

that looks like setting MMCONFIG through ATI chipset.

and cpu northbridge set 1M for accessing 1M...

BIOS really should only use northbridge MSR to set that to cover bus [0, 255]

and just disable the ATI pci 00:00.0 BAR3
