cd23e6923f x86: Remove coreboot start16 code
Now that coreboot doesn't need the start16 code, remove it. We need
to remove the CONFIG_SYS_X86_RESET_VECTOR option from coreboot.h also.

This prevents the preprocessor from complaining when processing
variadic macros

badcb343d7 x86: coreboot: Move non-board specific files to coreboot arch directory
coreboot.c and coreboot_pci.c don't contain board specific but only
coreboot specific code. Hence move it to the coreboot directory in
arch/x86/cpu (which should probably be moved out of cpu/ in another
commit)

63f559cd12 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.

ef5a5b0049 x86: Initial commit for running as a coreboot payload
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.
