2024-01-24device, security: Rename Makefiles from .inc to .mkMartin Roth
The .inc suffix is confusing to various tools as it's not specific to Makefiles. This means that editors don't recognize the files, and don't open them with highlighting and any other specific editor functionality. This issue is also seen in the release notes generation script where Makefiles get renamed before running cloc.

2022-02-07treewide: Remove "ERROR: "/"WARN: " prefixes from log messagesJulius Werner
Now that the console system itself will clearly differentiate loglevels, it is no longer necessary to explicitly add "ERROR: " in front of every BIOS_ERR message to help it stand out more (and allow automated tooling to grep for it). Removing all these extra .rodata characters should save us a nice little amount of binary size. This patch was created by running find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';' and doing some cursory review/cleanup on the result.

2020-12-14drivers: Replace multiple fill_lb_framebuffer with single instancePatrick Rudolph
Currently it's not possible to add multiple graphics drivers into one coreboot image. This patch series will fix this issue by providing a single API that multiple graphics drivers can use. This is required for platforms that have two graphic cards, but different graphic drivers, like Intel+Aspeed on server platforms or Intel+Nvidia on consumer notebooks. The goal is to remove duplicated fill_fb_framebuffer(), the advertisment of multiple independent framebuffers in coreboot tables, and better runtime/build time graphic configuration options. Replace all duplications of fill_fb_framebuffer and provide a single one in edid_fill_fb.c. Should not change the current behaviour as still only one graphic driver can be active at time.

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.

2013-07-10Provide support for setting up the framebuffer from EDIDRonald G. Minnich
Add three functions to edid.c: void set_vbe_mode_info_valid(struct edid *edid, uintptr_t fb_addr) takes an edid and uintptr_t, and fills in a static lb_framebuffer struct as well as setting the static vbe_valid to 1 unless some problem is found in the edid. The intent here is that this could be called from the native graphics setup code on both ARM and x86. int vbe_mode_info_valid(void) returns value of the static vbe_valid. void fill_lb_framebuffer(struct lb_framebuffer *framebuffer) copies the static edid_fb to lb_framebuffer. There is now a common vbe.h in src/include, removed the two special ones. In general, graphics in coreboot is a mess, but graphics is always a mess. We don't have a clean way to try two different ways to turn on a device and use the one that works. One battle at a time. Overall, things are much better.

2013-03-21ramstage: prepare for relocationAaron Durbin
The current ramstage code contains uses of symbols that cause issues when the ramstage is relocatable. There are 2 scenarios resolved by this patch: 1. Absolute symbols that are actually sizes/limits. The symbols are problematic when relocating a program because there is no way to distinguish a symbol that shouldn't be relocated and one that can. The only way to handle these symbols is to write a program to post process the relocations and keep a whitelist of ones that shouldn't be relocated. I don't believe that is a route that should be taken so fix the users of these sizes/limits encoded as absolute symbols to calculate the size at runtime or dereference a variable in memory containing the size/limit. 2. Absoulte symbols that were relocated to a fixed address. These absolute symbols are generated by assembly files to be placed at a fixed location. Again, these symbols are problematic because one can't distinguish a symbol that can't be relocated. The symbols are again resolved at runtime to allow for proper relocation. For the symbols defining a size either use 2 symbols and calculate the difference or provide a variable in memory containing the size.

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.
