From bc8613ecaf858419288f4cef784c562f3d8a5093 Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Wed, 25 Aug 2010 18:35:42 +0000 Subject: Fix i945 based boards - prevent GCC from inlining do_ram_command - it will break RAM initialization. - fix the PCIRST# mechanism in those boards that do it, it requires 200ms, not 200us - move PCIRST# as early as possible (before ich7_enable_lpc) Signed-off-by: Stefan Reinauer Acked-by: Corey Osgood git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5740 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 --- src/mainboard/getac/p470/romstage.c | 3 +-- src/mainboard/kontron/986lcd-m/romstage.c | 6 ++---- src/mainboard/roda/rk886ex/romstage.c | 5 +++-- 3 files changed, 6 insertions(+), 8 deletions(-) (limited to 'src/mainboard') diff --git a/src/mainboard/getac/p470/romstage.c b/src/mainboard/getac/p470/romstage.c index 451f5d9d8a..9f7c14af52 100644 --- a/src/mainboard/getac/p470/romstage.c +++ b/src/mainboard/getac/p470/romstage.c @@ -308,9 +308,8 @@ void main(unsigned long bist) #if 0 /* Force PCIRST# */ pci_write_config16(PCI_DEV(0, 0x1e, 0), BCTRL, SBR); - udelay(200); + udelay(200 * 1000); pci_write_config16(PCI_DEV(0, 0x1e, 0), BCTRL, 0); - udelay(200); #endif ich7_enable_lpc(); diff --git a/src/mainboard/kontron/986lcd-m/romstage.c b/src/mainboard/kontron/986lcd-m/romstage.c index 5faf699129..902e5c2679 100644 --- a/src/mainboard/kontron/986lcd-m/romstage.c +++ b/src/mainboard/kontron/986lcd-m/romstage.c @@ -366,14 +366,12 @@ void main(unsigned long bist) enable_lapic(); } - ich7_enable_lpc(); - /* Force PCIRST# */ pci_write_config16(PCI_DEV(0, 0x1e, 0), BCTRL, SBR); - udelay(200); + udelay(200 * 1000); pci_write_config16(PCI_DEV(0, 0x1e, 0), BCTRL, 0); - udelay(200); + ich7_enable_lpc(); early_superio_config_w83627thg(); /* Set up the console */ diff --git a/src/mainboard/roda/rk886ex/romstage.c b/src/mainboard/roda/rk886ex/romstage.c index 19b29053e3..00c4c9f446 100644 --- a/src/mainboard/roda/rk886ex/romstage.c +++ b/src/mainboard/roda/rk886ex/romstage.c @@ -279,11 +279,12 @@ void main(unsigned long bist) enable_lapic(); } - ich7_enable_lpc(); - /* Force PCIRST# */ pci_write_config16(PCI_DEV(0, 0x1e, 0), BCTRL, SBR); + udelay(200 * 1000); + pci_write_config16(PCI_DEV(0, 0x1e, 0), BCTRL, 0); + ich7_enable_lpc(); early_superio_config(); /* Set up the console */ -- cgit v1.2.3
