Marshall Dawson uploaded patch set #7 to the change originally created by Kyösti Mälkki.
arch/x86: Implement RESET_VECTOR_IN_RAM
Add support for devices with the reset vector pointing into DRAM.
Add a crt0 file that includes the traditional x86 reset code and
a new linker script that describes the early region definitions.
New Kconfig options allow the soc to determine the total early
DRAM storage required, as well as the BSP stack size.
The current implementation piggy-backs off of the romstage build
but does not require romstage to be in cbfs.
Similar to changes made when bootblock could begin executing C,
the extra _start label and gdt_init.S must be excluded.
