2016-02-19soc/intel/quark: Use single ID value for HSUART1Lee Leahy
Use single ID value for HSUART1. 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 successful if: * Debug serial output stays enabled after BS_DEV_RESOURCES state Change-Id: I38eca247f151e67c2b243a8a3bb21d9d1f4603de Signed-off-by: Lee Leahy <leroy.p.leahy@intel.com> Reviewed-on: https://review.coreboot.org/13734 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martinroth@google.com>
2016-02-18soc/intel/quark: Enable HSUART1Lee Leahy
Enable HSUART1 for debug serial output. Specify the fixed resources in the UART driver. This keeps debug serial output flowing during the rest of the device initialization. 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 successful if: * Debug serial output stays enabled after BS_DEV_RESOURCES state Change-Id: Ica02e5fece156b21d4a3889284ca467d55c7880d Signed-off-by: Lee Leahy <leroy.p.leahy@intel.com> Reviewed-on: https://review.coreboot.org/13730 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martinroth@google.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>
