commit 3d2edec20ac1715302b8758ab822206f45a44487 Author: Lee Leahy leroy.p.leahy@intel.com Date: Mon Feb 1 12:27:45 2016 -0800
mainboard/intel/galileo: Enable Serial Output
Add the code to enable debug serial output using HSUART1:
* Enable the code using Kconfig value ENABLE_BUILTIN_HSUART1 * Specify the portion of ESRAM to be used by romstage * Initialize the debug serial port
Testing: * Edit the src/mainboard/intel/galileo/Makefile.inc file * Add "select HAVE_FSP_PDAT_FILE" * Add "select HAVE_FSP_RAW_BIN" * Add "select HAVE_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
TEST=Build and run on Galileo
