2018-08-06soc/amd/stoneyridge: Enable spread spectrum in bootblockRaul E Rangel
setup_spread_spectrum is called in early_init, meaning the console is not initialized yet. So you won't see boot block booting twice. BUG=b:111610455 TEST=booted grunt and verified that AmdInitReset does not reboot. I had AGESA patched to skip the JTAG check.

2018-01-26amd/stoneyridge: Convert BiosRam access to MMIOMarshall Dawson
Change the BiosRam read/write functions to use the fixed MMIO range at 0xfed80500. This is faster than two accesses per byte when using I/O 0xcd4/0xcd5. Note that BiosRam may only be accessed byte-by-byte. It does not decode normally.
