2013-03-20x86: don't clear bss in ramstage entryAaron Durbin
The cbfs stage loading routine already zeros out the full memory region that a stage will be loaded. Therefore, it is unnecessary to to clear the bss again after once ramstage starts.

2013-03-19cbfs: alternative support for cbfs_load_payload()Aaron Durbin
In certain situations boot speed can be increased by providing an alternative implementation to cbfs_load_payload(). The ALT_CBFS_LOAD_PAYLOAD option allows for the mainboard or chipset to provide its own implementation. Booted baskingridge board with alternative and regular cbfs_load_payload().

2013-02-03armv7: Add 'bootblock' build class.Hung-Te Lin
For ARM platform, the bootblock may need more C source files to initialize UART / SPI for loading romstage. To preventing making complex and implicit dependency by using #include inside bootblock.c, we should add a new build class "bootblock". Also #ifdef __BOOT_BLOCK__ can be used to detect if the source is being compiled for boot block. For x86, the bootblock is limited to fewer assembly files so it's not using this class. (Some files shared by x86 and arm in top level or lib are also changed but nothing should be changed in x86 build process.)

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.

2012-05-04Make CBFS output more consistentStefan Reinauer
- Prefix all CBFS output messages with CBFS: - Add an option DEBUG_CBFS that is off by default. Without DEBUG_CBFS enabled, the code will no longer print all the files it walks for every file lookup. - Add DEBUG() macro next to LOG() and ERROR() to specify which messages should only be visible with DEBUG_CBFS printed. - Actually print a message when the file we're looking for was found. :) old: Searching for fallback/coreboot_ram Check cmos_layout.bin Check pci8086,0106.rom Check fallback/romstage Check fallback/coreboot_ram Change-Id: I2d731fae17a5f6ca51d435cfb7a58d6e017efa24 Stage: loading fallback/coreboot_ram @ 0x100000 (540672 bytes), entry @ 0x100000 Stage: done loading. new: CBFS: Looking for 'fallback/coreboot_ram' CBFS: found.

2011-08-04split CBFS support into shared core and extended functionsPatrick Georgi
The core is data structures and basic file finding capabilities, while option ROM handling, and loading stages and payloads is "extended". The core is rewritten to be BSD-l (its header already was), so can be copied to libpayload verbatim. It's also more robust in finding files in corrupted images, eg. after partial erase or update.

2009-08-2020090819-2-trim-down-cbfs:Patrick Georgi
CBFS uses sprintf, which requires vtxprintf, which requires (in the current design) a nested function. That works on x86, but on PPC this requires a trampoline. In the ROM stage, this is not available, so remove the single use of sprintf and replace it with a direct string handler - it's only used to fill in fixed-length hex values. 20090819-3-more-noreturns-in-romcc: Mark two more functions in romcc as noreturn.
