2013-11-25x86: use proper types for interrupt callbacksAaron Durbin
The mainboard_interrupt_handlers() argument for the function pointer was using void * as the type. This does not allow the compiler to catch type differences for the arguments. Thus, some code has been committed which violates the new interrupt callbacks not taking any arguments. Make sure the compiler provides a type checking benefit.

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. The best part: this code would also work for ARM, which also uses EDID. Change-Id: Id23eb61498b331d44ab064b8fb4cb10f07cff7f3 Signed-off-by: Ronald G.

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.

This hit me when running the latest Qemu with coreboot: First the graphics OPROM is running, then an iPXE OPROM. The iPXE OPROM has no int10 support (obviously) so calling vbe_set_graphics() wipes the framebuffer information from the coreboot table.

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.
