soc/intel/quark: Enable ESRAM
The Quark SoC uses ESRAM instead of cache-as-RAM. This code requires that utils/xcompile/xcompile change the machine architecture from i686 to i586 to ensure that the Quark does not attempt to execute unsupported instructions:
* Adjust Makefile.inc to add the RMU to the coreboot image * Add code to enable the ESRAM
Directly use the QuarkSocPkg/QuarkNorthCluster/Include/QuarkNcSocId.h file from the EDK2 tree (https://github.com/tianocore/edk2.git) to enable easy differences and correct issues in coreboot that were found in EDK2.
Testing on Galileo: * Edit the src/mainboard/intel/galileo/Makefile.inc file * Add "select ADD_RMU_FILE" * Place the rmu.bin file in the location specified by CONFIG_RMU_FILE * Remove power from the board * Apply power to the board * Testing is successful if the SD LED is on indicating that the end of esram_init.inc was reached
