From d75ed0bfd9238b210fdca136784cd699696421c7 Mon Sep 17 00:00:00 2001 From: Lee Leahy Date: Fri, 4 Mar 2016 16:49:40 -0800 Subject: soc/intel/quark: Disable the ROM shadow Disable the ROM shadow and enable RAM for 0x000e0000 - 0x000fffff. 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 * Testing successful display of 0x000ffff0 - 0x000fffff does not match the end of the SPI flash.
