Coreboot

Coreboot, formerly known as LinuxBIOS, provides a modern BIOS/firmware implementation for many modern processors and chipsets.

mb/google/corsola: Add an option for SD card initialization
Rex-BC Chen: There is no support for SD card on Corsola reference board, so we add a configuration to disable SD card initialization to prevent setting GPIOs in a mistaken way.

mb/google/corsola: Add VPROC12/VSRAM_PROC12 to regulator interface
Rex-BC Chen: Add VPROC12/VSRAM_PROC12 to adjust power for raising little CPU frequency.

soc/mediatek/mt8186: Add support for regulator VPROC12/VSRAM_PROC12
Rex-BC Chen: To raise little CPU frequency, add support for VPROC12 and VSRAM_PROC12 of MT6366.

ec/google/chromeec: Support 5 temperature sensors
Tim Wawrzynczak: Some boards with the chrome EC will need to support more than 4 temperature sensors, so modify the number of TSRs supported when generating the ACPI code.

dptf: Add support for one more temperature sensor
Tim Wawrzynczak: Some boards may use more than 4 temperature sensors for DPTF thermal control, so this patch adds support for one more temperature sensor.

util/testing: Add ifdtool to tools to be tested
Patrick Georgi: Ensure that the separate Makefile doesn't break.
