From 5c10abeb734d8adee217bc5ed1edcb042064d239 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Tue, 15 Mar 2016 07:44:49 +0100 Subject: nb/intel/sandybridge: increase MMCONF_BASE_ADDRESS Set MMCONF_BASE_ADDRESS to 0xf8000000. It was already done for some boards, but not all. The sandybridge chipset code assumes 64 pci buses behind MMCONF. Therefore, only 64MiB of physical address space is required. Increasing the address allows to use additional 128MiB of MMIO space and to use the Intel IGD and a PEG at the same time. Previously it wasn't possible to use both at the same time, as two 256MiB areas won't fit into MMIO space. Test system: * Gigabyte GA-B75M-D3H * Intel Pentium CPU G2130 * Onboard GPU Intel IvyBridge Desktop * PEG GPU AMD RV770 Change-Id: I3bf72439056c8089ada6899bb0605e5cd9d89cd6 Signed-off-by: Patrick Rudolph Reviewed-on: https://review.coreboot.org/14096 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin Reviewed-by: Philipp Deppenwiese --- src/mainboard/gigabyte/ga-b75m-d3h/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/mainboard/gigabyte/ga-b75m-d3h/Kconfig') diff --git a/src/mainboard/gigabyte/ga-b75m-d3h/Kconfig b/src/mainboard/gigabyte/ga-b75m-d3h/Kconfig index 987c8b7120..e53b68c0a3 100644 --- a/src/mainboard/gigabyte/ga-b75m-d3h/Kconfig +++ b/src/mainboard/gigabyte/ga-b75m-d3h/Kconfig @@ -20,7 +20,7 @@ config BOARD_SPECIFIC_OPTIONS config MMCONF_BASE_ADDRESS hex - default 0xf0000000 + default 0xf8000000 config DRAM_RESET_GATE_GPIO int -- cgit v1.2.3
