20 Nov '15

Damien Zammit (damien(a)zamaudio.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10074 -gerrit commit 33c2429634d75ebfb249794ee8eada0d5afb556e Author: Damien Zammit <damien(a)zamaudio.com> Date: Mon May 4 10:41:21 2015 +1000 mainboard/intel/d510mo: Add Intel D510MO mainboard Board uses Pineview native raminit Board boots grub -> linux kernel NB: For fully functional board, this currently needs patch: 6311, otherwise board gets stuck on parallel SMI init. VGA needs work, currently headless machine.

Patch set updated for coreboot: mainboard/intel/d510mo: Add Intel D510MO mainboard
by Damien Zammit 20 Nov '15

20 Nov '15

Damien Zammit (damien(a)zamaudio.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10074 -gerrit commit a7a098a4b96f812da4d0cd88e890b54dac3724c5 Author: Damien Zammit <damien(a)zamaudio.com> Date: Mon May 4 10:41:21 2015 +1000 mainboard/intel/d510mo: Add Intel D510MO mainboard Board uses Pineview native raminit Board boots grub -> linux kernel NB: For fully functional board, this currently needs patch: 6311, otherwise board gets stuck on parallel SMI init. VGA needs work, currently headless machine.

Patch set updated for coreboot: AMD/Bettong: DSDT table: Reserved MMIO space for FCH

Zheng Bao (zheng.bao(a)amd.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/11747 -gerrit commit 93c6fb27626d8c77df88b56154c1f2515000372f Author: Zheng Bao <fishbaozi(a)gmail.com> Date: Fri Nov 20 16:07:34 2015 +0800 AMD/Bettong: DSDT table: Reserved MMIO space for FCH In current code, \_SB.PCI0 declare MMIO between TOM1 and 4GB. This is not correct because higher MMIO space is reserved by \_SB rather than \_SB.PCI0. For example: [0xFEDC2000 - 0xFEDC5FFF] reserved for FCH I2C [0xFEDC6000 - 0xFEDC8FFF] reserved for FCH UART Change-Id: I922d8c6a8ff1433582c70f86d5636171394af283 Signed-off-by: WANG Siyuan <wangsiyuanbuaa(a)gmail.com> Signed-off-by: WANG Siyuan <SiYuan.Wang(a)amd.com> Signed-off-by: Zheng Bao <fishbaozi(a)gmail.com> --- src/southbridge/amd/pi/hudson/acpi/fch.asl | 3 +++ 1 file changed, 3 insertions(+) diff --git a/src/southbridge/amd/pi/hudson/acpi/fch.asl b/src/southbridge/amd/pi/hudson/acpi/fch.asl index 02a272d..18b4da2 100644 --- a/src/southbridge/amd/pi/hudson/acpi/fch.asl +++ b/src/southbridge/amd/pi/hudson/acpi/fch.asl @@ -108,6 +108,9 @@ Name(CRES, ResourceTemplate() { /* memory space for PCI BARs below 4GB */ Memory32Fixed(ReadOnly, 0x00000000, 0x00000000, MMIO) + + /* Reserved for FCH. 0xFED40000 - 0xFEDD0000 */ + Memory32Fixed(ReadOnly, 0xFED40000, 0x00090000, FCHR) }) /* End Name(_SB.PCI0.CRES) */ Method(_CRS, 0) {
