2016-02-10soc/intel/quark: MTRR supportLee Leahy
Add the SoC specific routines to access the MTRR registers. These registers exist in the host bridge and are not accessible via the rdmsr/wrmsr instructions. 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" * Add "select DISPLAY_MTRRS" * 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 * Testing is successful if: * The message "FSP TempRamInit successful" is displayed Change-Id: I7c124145429ae1d1365a6222a68853edbef4ff69 Signed-off-by: Lee Leahy <leroy.p.leahy@intel.com> Reviewed-on: https://review.coreboot.org/13530 Tested-by: build bot (Jenkins) Reviewed-by: FEI WANG <wangfei.jimei@gmail.com>
2016-02-09soc/intel/quark: Enable Serial PortLee Leahy
Add the code to enable debug serial output using HSUART1: * Enable the code using Kconfig value ENABLE_BUILTIN_HSUART1 * Note that the BIST value is always zero as validated in esram_init.inc * The initial TSC value is currently not saved! 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 * Testing is successful if serial output is present on HSUART1 at 115200 baud, 8-bit, no parity Change-Id: I7e6181e8b9bc901c3ab236f0b56534850bb6bfd0 Signed-off-by: Lee Leahy <leroy.p.leahy@intel.com> Reviewed-on: https://review.coreboot.org/13445 Tested-by: build bot (Jenkins) Reviewed-by: FEI WANG <wangfei.jimei@gmail.com>
2016-02-08soc/intel/quark: Add TempRamInit supportLee Leahy
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.
