M4A785T-M: fix TOM2.
This commit is based on the commit 94fa3db36688e8db133aebe14d480b0c4722e4c9 (AMD Mahogany Fam10 ACPI table fixes.) With commit permit to boot without pci=nocrs on the M4A785T-M board. Before the fix dmesg contained the following: [ 0.452071] ACPI Error: [TOM2] Namespace lookup failure, AE_NOT_FOUND (20110112/psargs-359) [ 0.480085] ACPI Error: [TOM2] Namespace lookup failure, AE_NOT_FOUND (20110112/psargs-359) [ 0.788222] ACPI Error: [TOM2] Namespace lookup failure, AE_NOT_FOUND (20110112/psargs-359) Now it only contains: [ 0.312102] TOM: 0000000080000000 aka 2048M Change-Id: I5d517604abe938af19b70d57d92c1f973114c1cd Signed-off-by: Denis 'GNUtoo' Carikli <GNUtoo@no-log.org> Reviewed-on: http://review.coreboot.org/635 Tested-by: build bot (Jenkins) Reviewed-by: Kerry Sheh <shekairui@gmail.com> Reviewed-by: Marc Jones <marcj303@gmail.com>
