2014-12-30libpayload: Provide selfboot function.Hung-Te Lin
The calling convention of payload entry function is different by architecture. For example, X86 takes no arguments and ARM needs first param to be a cb_header_ptr*. To help payloads load and execute other payloads easily and correctly, we should provide the selfboot() function in libpayload, using same prototype as defined in coreboot environment.

2014-08-05libpayload: Change CONFIG_* to CONFIG_LP_* in the kconfig.Gabe Black
When libpayload header files are included in the payload itself, it's possible that the payloads config settings will conflict with the ones in libpayload. It's also possible for the libpayload config settings to conflict with the payloads. To avoid that, the libpayload config settings have _LP_ (for libpayload) added to them. The symbols themselves as defined in the Config.in files are still the same, but the prefix added to them is now CONFIG_LP_ instead of just CONFIG_.

2013-03-29libpayload: add x86 ROM variable MTRR supportAaron Durbin
On x86, coreboot may allocate a variable range MTRR for enabling caching of the system ROM. Add the ability to parse this structure and add the result to the sysinfo structure. An example usage implementation would be to obtain the variable MTRR index that covers the ROM from the sysinfo structure. Then one would disable caching and change the MTRR type from uncacheable to write-protect and enable caching. The opposite sequence is required to tearn down the caching.

2013-03-14libpayload: Generalize and redistribute timekeeping codeGabe Black
The timekeeping code in libpayload was dependent on rdtsc, and when it was split up by arch, that code was duplicated even though it was mostly the same. This change factors out actually reading the count from the timer and the speed of the timer and puts the definitions of ndelay, udelay, mdelay and delay into generic code. Then, in x86, the timer_hz and timer_get_raw_value functions which used to be in depthcharge were moved over to libpayload's arch/x86/timer.c. In ARM where there isn't a single, canonical timer, those functions are omitted with the intention that they'll be implemented by a specific timer driver chosen elsewhere.

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.
