From d6cc617e171ddcaf83a8b6025d79025e13ba0cbb Mon Sep 17 00:00:00 2001 From: Damien Zammit Date: Mon, 13 Jul 2015 15:27:01 +1000 Subject: gigabyte/ga-b75m-d3h: Update device tree This patch resolves the outstanding issues with PCI device enumeration and getting the board to boot into GNU/Linux with VGA rom. Previously the board would not boot to GNU/Linux with video, even if VGA rom was used. Bugs in the devicetree were fixed according to superiotool output. Tested on GA-B75M-D3H with VGA rom. Booted to GNU/Linux (Fedora 22 4.0.4-301.fc22.x86_64) Change-Id: Ide1f406652659e6f99ee5d993719c187650fffe4 Signed-off-by: Damien Zammit Reviewed-on: http://review.coreboot.org/10895 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel Reviewed-by: Felix Held Reviewed-by: Alexandru Gagniuc --- src/mainboard/gigabyte/ga-b75m-d3h/devicetree.cb | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) (limited to 'src') diff --git a/src/mainboard/gigabyte/ga-b75m-d3h/devicetree.cb b/src/mainboard/gigabyte/ga-b75m-d3h/devicetree.cb index 19a476cf49..f4a8664849 100644 --- a/src/mainboard/gigabyte/ga-b75m-d3h/devicetree.cb +++ b/src/mainboard/gigabyte/ga-b75m-d3h/devicetree.cb @@ -24,7 +24,7 @@ chip northbridge/intel/sandybridge device pci 00.0 on # host bridge subsystemid 0x1458 0x5000 end - device pci 01.0 off end # PCIe Bridge for discrete graphics + device pci 01.0 on end # PCIe Bridge for discrete graphics device pci 02.0 on # vga controller subsystemid 0x1458 0xd000 end @@ -58,7 +58,7 @@ chip northbridge/intel/sandybridge device pci 1b.0 on # High Definition Audio subsystemid 0x1458 0xa002 end - device pci 1c.0 off end # PCIe Port #1 + device pci 1c.0 on end # PCIe Port #1 device pci 1c.1 off end # PCIe Port #2 device pci 1c.2 off end # PCIe Port #3 device pci 1c.3 off end # PCIe Port #4 @@ -92,17 +92,19 @@ chip northbridge/intel/sandybridge drq 0x74 = 4 end device pnp 2e.4 on # EC + io 0x60 = 0xa30 irq 0x70 = 9 + io 0x62 = 0xa20 end device pnp 2e.5 on # Keyboard + io 0x60 = 0x60 irq 0x70 = 1 + io 0x62 = 0x64 end device pnp 2e.6 on # Mouse irq 0x70 = 12 end - device pnp 2e.7 on # GPIO - irq 0x70 = 0 - end + device pnp 2e.7 off end # GPIO device pnp 2e.a off end # IR end end -- cgit v1.2.3
