x86: Import code from coreboot's libpayload to parse the coreboot table
This change also forces the lib_sysinfo structure to be in the .data section. Otherwise it ends up in the .bss section. U-boot assumes that it doesn't need to copy it over during relocation, and instead fills that whole section with zeroes. If we really were booting from ROM that would be appropriate, but we need some information from the coreboot tables (memory size) before then and have to fill that structure before relocation. We skirt u-boot's assumption by putting this in .data where it assumes there is still read only but non-zero data. Signed-off-by: Gabe Black <gabeblack@chromium.org>
