2023-09-06device/pci_rom: Set VBIOS checksum when filling VFCT tableMatt DeVillier
AMD's Windows display drivers validate the checksum of the VBIOS data in the VFCT table (which gets modified by the FSP GOP driver), so ensure it is set correctly after copying the VBIOS into the table if the FSP GOP driver was run. Without the correct checksum, the Windows GPU drivers will fail to load with a code 43 error in Device Manager. Thanks to coolstar for root causing the issue. TEST=build/boot Win11 on google/skyrim (frostflow), ensure GPU driver loaded and functional.

2023-03-09device/pci_rom: rework PCI ID remapping in pci_rom_probeFelix Held
Only call cbfs_boot_map_optionrom/cbfs_boot_map_optionrom_revision once and pass the already remapped PCI ID to it. This avoids the spurious warning that the CBFS file wasn't found from the first cbfs_boot_map_optionrom call in cases where the PCI ID needs to be remapped to get the right ID for which a file in CBFS exists.

This change moves all ACPI table support in coreboot currently living under arch/x86 into common code to make it architecture independent.

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.

The Kconfig option "ON_DEVICE_ROM_RUN" suggests that PCI Option ROMs are run, but in fact it only controls the loading of PCI based Option ROMs. At the moment coreboot only executes Option ROMs if they are VGA Options ROMs and the VGA Option ROM execution flag is enabled. Setting ON_DEVICE_ROM_RUN with VGA Option ROM execution disabled has no effect. Clarify that this flag controls the loading behaviour and not the execution behaviour.

2015-06-02cbfs: new API and better program loadingAaron Durbin
A new CBFS API is introduced to allow making CBFS access easier for providing multiple CBFS sources. That is achieved by decoupling the cbfs source from a CBFS file. A CBFS source is described by a descriptor. It contains the necessary properties for walking a CBFS to locate a file. The CBFS file is then decoupled from the CBFS descriptor in that it's no longer needed to access the contents of the file. All of this is accomplished using the regions infrastructure by repsenting CBFS sources and files as region_devices. Because region_devices can be chained together forming subregions this allows one to decouple a CBFS source from a file. This also allows one to provide CBFS files that came from other sources for payload and/or stage loading. The program loading takes advantage of those very properties by allowing multiple sources for locating a program. Because of this we can reduce the overhead of loading programs because it's all done in the common code paths. Only locating the program is per source.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

2013-01-30Extend CBFS to support arbitrary ROM source media.Hung-Te Lin
Summary: Isolate CBFS underlying I/O to board/arch-specific implementations as "media stream", to allow loading and booting romstage on non-x86. CBFS functions now all take a new "media source" parameter; use CBFS_DEFAULT_MEDIA if you simply want to load from main firmware. API Changes: cbfs_find => cbfs_get_file. cbfs_find_file => cbfs_get_file_content. cbfs_get_file => cbfs_get_file_content with correct type. CBFS used to work only on memory-mapped ROM (all x86). For platforms like ARM, the ROM may come from USB, UART, or SPI -- any serial devices and not available for memory mapping. To support these devices (and allowing CBFS to read from multiple source at the same time), CBFS operations are now virtual-ized into "cbfs_media". To simplify porting existing code, every media source must support both "reading into pre-allocated memory (read)" and "read and return an allocated buffer (map)". For devices without native memory-mapped ROM, "cbfs_simple_buffer*" provides simple memory mapping simulation. Every CBFS function now takes a cbfs_media* as parameter. CBFS_DEFAULT_MEDIA is defined for CBFS functions to automatically initialize a per-board default media (CBFS will internally calls init_default_cbfs_media). Also revised CBFS function names relying on memory mapped backend (ex, "cbfs_find" => actually loads files). Now we only have two getters: struct cbfs_file *entry = cbfs_get_file(media, name); void *data = cbfs_get_file_content(CBFS_DEFAULT_MEDIA, name, type); Test results: - Verified to work on x86/qemu. - Compiles on ARM, and follow up commit will provide working SPI driver.
