2013-03-12libpayload: Fix reading x86 CBFS images from RAMPatrick Georgi
Three issues: 1. the hardcoded dereferenced pointer at 0xfffffffc 2. "RAM media" has no idea about ROM relative addresses 3. off-by-one in RAM media: it's legal to request 4 bytes from 0xfffffffc Change-Id: I671ac12d412c71dc8e8e6114f2ea13f58dd99c1d Signed-off-by: Patrick Georgi <patrick@georgi-clan.de> Reviewed-on: http://review.coreboot.org/2624 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Hung-Te Lin <hungte@chromium.org>
2013-02-12libpayload: New CBFS to support multiple firmware media sources.Hung-Te Lin
Upgrade CBFS in libpayload to use new media-based implementation from coreboot ( http://review.coreboot.org/#/c/2182/ ). Old CBFS functions (cbfs_find, cbfs_find_file, get_cbfs_header) are still supported, although the recommended way is to use new CBFS API. To migrate your existing x86 payload source: - Change cbfs_find to cbfs_get_file - Change cbfs_find_file to cbfs_get_file_content - Prefix every CBFS call with a CBFS_DEFAULT_MEDIA argument. Ex, char *jpeg_data = cbfs_find_file("splash.jpg", CBFS_TYPE_BOOTSPLASH); => char *jpeg_data = cbfs_get_file_content( CBFS_DEFAULT_MEDIA, "splash.jpg", CBFS_TYPE_BOOTSPLASH); The legacy setup_cbfs_from_{ram,flash} is also supported, although the better equivalent is to make a new media instance: struct cbfs_media ram_media; init_cbfs_ram_media(&ram_media, start, size); char *data = cbfs_get_file_content(&ram_media, "myfile", my_type); Verified by being successfully linked with filo.

2012-11-08Refactor the endianness conversion functions and header files.Gabe Black
The endianness of an architecture is now set up automatically using Kconfig and some common code. The available conversion functions were also expanded to go to or from a particular endianness. Those use the abbreviation le or be for little or big endian. Built for Stumpy and saw coreinfo cbfs support work which uses network byte order. Used the functions which convert to little endian to implement an AHCI driver. The source arch is also little endian, so they were effectively (and successfully) inert.

Two new functions allow switching the CBFS functions from using RAM or ROM, with ROM as default.

Add cbfs core from coreboot into libpayload, and to support lzma decode, add coreboot's lzma code, too. Carl-Daniel agreed to relicense the lzmadecode wrapper as BSD-l, solving licensing problems.
