2013-06-04DDR3: Add utilities for creating MRS commandsAlexandru Gagniuc
MRS commands are used to tell the DRAM chip what timing and what termination and drive strength to use, along with other parameters. The MRS commands are defined by the DDR3 specification [1]. This makes MRS commands hardware-independent. MRS command creation is duplicated in various shapes and forms in any chipset that does DDR3. This is an effort to create a generic MRS API that can be used with any chipset. This is used in the VX900 branch.

In the process of streamlining coreboot code and getting rid of unneeded ifdefs, drop a number of unneeded checks for the GNU C compiler. This also cleans up x86emu/types.h significantly by dropping all the duplicate types in there.

2013-04-03Add PXE ROM selection to Kconfig menuSiyuan Wang
Adding a pxe rom manually is inconvenient. With this patch, PXE ROM can be added automatically by selecting PXE_ROM in Kconfig. I have tested this patch on AMD Parmer and Thatcher with iPXE. iPXE would be a boot device in Seabios when pressing F12. iPXE works well with coreboot and Seabios.

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.

2013-03-15Google Link: Add remaining code to support native graphicsRonald G. Minnich
The Link native graphics commit 49428d84 [1] Add support for Google's Chromebook Pixel was missing some of the higher level bits, and hence could not be used. This is not new code -- it has been working since last August -- so the effort now is to get it into the tree and structure it in a way compatible with upstream coreboot. 1. Add options to src/device/Kconfig to enable native graphics. 2. Export the MTRR function for setting variable MTRRs. 3. Clean up some of the comments and white space. While I realize that the product name is Pixel, the mainboard in the coreboot tree is called Link, and that name is what we will use in our commits.

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.
