libpayload: New CBFS to support multiple firmware media sources.
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.
