T124: perform ram_repair when CPU rail is powered on in warmboot
This patch is to perform software triggered RAM re-repair in the warm boot path. "RAM" actually refers to the CPU cache here (yeah, I know, but that's how the manuals call it). This is some magic hardware thing that must be done every time after applying power to the main CPU cores or their cache may have random failures in some very rare cases. Also, note that this file isn't built in coreboot proper, but is a companion binary for kernel. It resides here for safe keeping.
