[coreboot] 4 GB RAM failure on DBM690T target (690G/SB600)

[Carl-Daniel Hailfinger]

Hi,

I'm using a slightly modified DBM690T target to boot my Asus M2A-VM
(690G/SB600) board.

Booting with 4 GB RAM (2x2) into Linux fails with lots of ACPI errors
because the ACPI code for DBM690T hardcodes 1 GB of RAM and has the code
paths for >4 GB commented out.

My attempts to fix this have been unsuccessful.

Was the DBM690T ever tested with 4 GB RAM and did it boot into Linux?

Regards,
Carl-Daniel
