commit dfee8dd33e7657210e2d3813f77ad42868308119
Author: Lee Leahy <leroy.p.leahy at intel.com>
Date:   Sun Feb 21 16:04:53 2016 -0800

    soc/intel/quark: Initialize some of the FADT base registers
    
    Initialize the base addresses for:
    *  Power management control
    *  Power management status
    *  Reset
    *  Power management timer
    *  General-Purpose Event 0
    
    Testing on Galileo:
    *  Edit the src/mainboard/intel/galileo/Makefile.inc file:
       *  Add "select ADD_FSP_PDAT_FILE"
       *  Add "select ADD_FSP_RAW_BIN"
       *  Add "select ADD_RMU_FILE"
    *  Place the FSP.bin file in the location specified by CONFIG_FSP_FILE
    *  Place the pdat.bin files in the location specified by
    CONFIG_FSP_PDAT_FILE
    *  Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
    *  Build EDK2 CorebootPayloadPkg/CorebootPayloadPkgIa32.dsc to generate
    UEFIPAYLOAD.fd
    *  Edit .config file and add the following lines:
       * CONFIG_PAYLOAD_ELF=y
       * CONFIG_PAYLOAD_FILE="path to UEFIPAYLOAD.fd"
    *  Testing successful when:
       *  Register address are properly displayed by the payload
