2019-03-04device/mmio.h: Add include file for MMIO opsKyösti Mälkki
MMIO operations are arch-agnostic so the include path should not be arch/.

2019-01-30soc/amd/stoneyridge: Access SMBUS through MMIORichard Spiegel
Currently SMBUS registers are accessed through IO, but with stoneyridge they can be accessed through MMIO. This reduces the time of execution by a tiny amount (MMIO write is faster than IO write, though MMIO read is about as fast as IO read) as most of the time consumed is actually transaction time. Convert code to MMIO access. BUG=b:117754784 TEST=Used IO to write and MMIO to read, to confirm a one to one relationship between IO and MMIO. Then build and boot grunt.

2018-12-03soc/amd/stoneyridge: Create MMIO ACPI access functionsRichard Spiegel
Now that the relationship between IO access and MMIO access has been established, create read/write functions to access ACPI standard registers through MMIO.

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.
