2013-03-22libpayload: Add comments on virtual pointers in lib_sysinfoNico Huber
After another incident related to virtual pointers in lib_sysinfo (and resulting confusion), I decided to put some comments on the matter into the code. Remember, we decided to always use virtual pointers in lib_sysinfo, but it's not always obvious from the code, that they are.

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.

2012-11-15libpayload: Always use virtual pointers in struct sysinfo_tNico Huber
We had mixed virtual and physical pointers in struct sysinfo_t. Some being virtual by accident which led to problems when we tried to reinitialize lib_sysinfo after relocating FILO (to get intentionally virtual pointers valid again). I guess this didn't cause much trouble before, as lib_get_sysinfo() was always called with physical addresses being equal to their virtual counterparts. For FILO, two possibilities seem practical: Either, have all pointers in struct sysinfo_t physical, so relocation doesn't hurt. Or, have all pointers virtual and call lib_get_sysinfo() again after relocation. This patch goes the latter way, changing the following pointers for situations where virtual pointers differ from physical: .extra_version .build .compile_time .compile_by .compile_host .compile_domain .compiler .linker .assembler .cb_version .vdat_addr .tstamp_table .cbmem_cons .mrc_cache We could also just correct the accidentally virtual pointers. But, IMO, this would lower the risk of future confusion. Note 1: Looks like .version gets never set. Note 2: .option_table and .framebuffer were virtual pointers but treated like physical ones. Even in FILO, this led to no problems as they were set before relocation.
