2018-01-31device/pci_rom: Write _ROM method for VGA devicesPatrick Rudolph
Write _ROM method and store PCI Option ROM in CBMEM. Allows an EFI compatible OS to retrieve the Option ROM without the need to access the PCI BAR. As the Option ROM is no longer present in the legacy VGA area it's required for mobile platforms. On hybrid devices, like Lenovo Thinkpads supporting NVIDIA Optimus it's the only way to retrieve the Option ROM, even with legacy BIOS, as there's no PCI BAR to map. Tested on: * Lenovo T530 * Linux Kernel 4.13.7 * nouveau Change-Id: I548b730fb64833083cc05af5b21dd6959804224b Signed-off-by: Patrick Rudolph <siro@das-labor.org> Reviewed-on: https://review.coreboot.org/20548 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org>

2015-04-21Unify byte order macros and clrsetbitsJulius Werner
This patch removes quite a bit of code duplication between cpu_to_le32() and clrsetbits_le32() style macros on the different architectures. This also syncs those macros back up to the new write32(a, v) style IO accessor macros that are now used on ARM and ARM64. CQ-DEPEND=CL:254862 BRANCH=none BUG=chromium:444723 TEST=Compiled Cosmos, Daisy, Blaze, Falco, Pinky, Pit, Rambi, Ryu, Storm and Urara. Booted on Jerry. Tried to compare binary images... unfortunately something about the new macro notation makes the compiler evaluate it more efficiently (not recalculating the address between the read and the write), so this was of limited value.

2012-02-07Add OPROM mapping support to corebootStefan Reinauer
This allows to add a PCI ID mapping function for option roms so that the same option rom can be used for a series of devices / PCI IDs. Intel and AMD often use the same option rom for a number of PCI devices with differend IDs. A function to implement such a mapping could look like this (or anything else appropriate): /* some vga option roms are used for several chipsets but they only have one * PCI ID in their header. If we encounter such an option rom, we need to do * the mapping ourselfes */ u32 map_oprom_vendev(u32 vendev) { u32 new_vendev=vendev; switch(vendev) { case 0xa0118086: new_vendev=0xa0018086; break; } return new_vendev; } Change-Id: I1be7fe113b895075d43ea48fe706b039cef136d2 Reviewed-on: http://review.coreboot.org/573 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.
