google/butterfly: Drop MRC.bin in favor of native raminit
I thought this wasn't going to work, and observing the timC detection failure of early tests, I was getting somewhat discouraged; however, this works. I've tried it with all possible permutations of the following memory modules: * 2 GiB single-rank DDR3-1600 * 4 GiB single-rank DDR3-1600 * 4 GiB dual-rank DDR3-1600 I did notice a limited number of memtest errors during one of the runs, but they were in an address range that is otherwise marked as reserved. I wrote that off as "maybe something was doing MMIO there just when memtest was poking the address range". I was not able to reproduce that error.
