x86: Add infrastructure to extract an e820 table from the coreboot tables

2011-12-19T02:26:16Z

Also approximate the size of RAM using the largest RAM address available in the tables. There may be areas which are marked as reserved which are actually at the end of RAM. Signed-off-by: Gabe Black

x86: Import code from coreboot's libpayload to parse the coreboot table

2011-12-19T02:26:15Z

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

x86: Initial commit for running as a coreboot payload

2011-12-19T02:26:15Z

Add a target for running u-boot as a coreboot payload in boards.cfg, a board, CPU and a config. This is a skeleton implementation which always reports the size of memory as 64 MB. Signed-off-by: Gabe Black
