soc/intel/quark: Add TempRamInit support
Successfully invoke TempRamInit from the FSP binary:
* Don't relocate the FSP binary image
* Copy the FSP binary into ESRAM
* Specify Kconfig values to easily debug ESRAM and TempRamInit code
* Specify the FSP binary file location
* Specify the FSP binary image ID
* Specify where in the flash image the FSP image must reside
* Specify the FSP data file location
* Specify where to place the FSP data file in the flash image
* Specify where in the ESRAM the FSP image must reside
Test 1 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"
* Add "select ENABLE_DEBUG_LED_FINDFSP"
* Place the FSP.bin file in the location specified by CONFIG_FSP_FILE
* Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
* Testing is successful if the SD LED is on indicating that the FSP.bin
file was properly located, The test fails if the SD LED is flashing.
Test 2 on Galileo:
* Edit the src/mainboard/intel/galileo/Makefile.inc file
* Remove "select ENABLE_DEBUG_LED_FINDFSP"
* Add "select ENABLE_DEBUG_LED_TEMPRAMINIT"
* Testing is successful if the SD LED is on indicating that the FSP.bin
file was properly located, The test fails if the SD LED is flashing.
