[coreboot] [PATCH] Make RAM check configurable via Kconfig

[ron minnich]

I'm being foolish, forgetting a lesson from Plan 9 style.

This will work fine:
if (RAMTEST) {
    ram_test(0, 640*1024);
    ram_test(whatever);
}

The compiler will optimize out the whole block if RAMTEST is 0.

I think this best.
