From d7549024098af093785151261266a02be19af633 Mon Sep 17 00:00:00 2001 From: Graeme Russ Date: Sun, 23 Aug 2009 12:59:50 +1000 Subject: i386: Misc PCI fixups Change PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY (Originally done in commit ff4e66e93c1a, regressed by commit 6d7f610b09f8) Cast PCI_ROM_ADDRESS_MASK to u32 Wrap probe_pci_video() call inside #ifdef CONFIG_VIDEO Change call to pci_find_class() to pci_find_devices(). This is based on a patch submitted on 1st March 2007 (Patch that fixes the compilation errors for sc520_cdp board) by mushtaq_k This patch requires that PCI_VIDEO_VENDOR_ID and PCI_VIDEO_DEVICE_ID be specified in the board config file. Dummy values have been added for the SC520 CDP board to enable compilation, but since I do not have one of these, I do know what the values should be Signed-off-by: Graeme Russ --- lib_i386/pci.c | 2 +- lib_i386/video_bios.c | 18 +++++++++--------- 2 files changed, 10 insertions(+), 10 deletions(-) (limited to 'lib_i386') diff --git a/lib_i386/pci.c b/lib_i386/pci.c index 4331b0441..f366bdc67 100644 --- a/lib_i386/pci.c +++ b/lib_i386/pci.c @@ -60,7 +60,7 @@ int pci_shadow_rom(pci_dev_t dev, unsigned char *dest) vendor, device, class_code); #endif /* Enable the rom addess decoder */ - pci_write_config_dword(dev, PCI_ROM_ADDRESS, PCI_ROM_ADDRESS_MASK); + pci_write_config_dword(dev, PCI_ROM_ADDRESS, (u32)PCI_ROM_ADDRESS_MASK); pci_read_config_dword(dev, PCI_ROM_ADDRESS, &addr_reg); if (!addr_reg) { diff --git a/lib_i386/video_bios.c b/lib_i386/video_bios.c index ce96a3e05..c8060e60a 100644 --- a/lib_i386/video_bios.c +++ b/lib_i386/video_bios.c @@ -76,18 +76,22 @@ void print_bios_bios_stat(void) } #endif +#ifdef CONFIG_VIDEO + #define PCI_CLASS_VIDEO 3 #define PCI_CLASS_VIDEO_STD 0 #define PCI_CLASS_VIDEO_PROG_IF_VGA 0 +static struct pci_device_id supported[] = { + {PCI_VIDEO_VENDOR_ID, PCI_VIDEO_DEVICE_ID}, + {} +}; static u32 probe_pci_video(void) { pci_dev_t devbusfn; - if ((devbusfn = pci_find_class(PCI_CLASS_VIDEO, - PCI_CLASS_VIDEO_STD, - PCI_CLASS_VIDEO_PROG_IF_VGA, 0)) != -1) { + if ((devbusfn = pci_find_devices(supported, 0) != -1)) { u32 old; u32 addr; @@ -103,7 +107,7 @@ static u32 probe_pci_video(void) /* Test the ROM decoder, do the device support a rom? */ pci_read_config_dword(devbusfn, PCI_ROM_ADDRESS, &old); - pci_write_config_dword(devbusfn, PCI_ROM_ADDRESS, PCI_ROM_ADDRESS_MASK); + pci_write_config_dword(devbusfn, PCI_ROM_ADDRESS, (u32)PCI_ROM_ADDRESS_MASK); pci_read_config_dword(devbusfn, PCI_ROM_ADDRESS, &addr); pci_write_config_dword(devbusfn, PCI_ROM_ADDRESS, old); @@ -133,11 +137,6 @@ static u32 probe_pci_video(void) return 0; } - -#endif - -#ifdef CONFIG_VIDEO - static int probe_isa_video(void) { u32 ptr; @@ -220,3 +219,4 @@ int video_bios_init(void) } #endif +#endif -- cgit v1.2.3
