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.
