Leroy P Leahy (leroy.p.leahy@intel.com) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/13509 -gerrit commit 621f68edf19c46cff7afcacf9aaba77be0971cb6 Author: Lee Leahy <leroy.p.leahy@intel.com> Date: Tue Jan 26 15:20:45 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 Change-Id: I91bf5257bd841ce9aa486887b35218336462ebea Signed-off-by: Lee Leahy <leroy.p.leahy@intel.com> --- src/mainboard/intel/galileo/Kconfig | 9 +++++++++ src/mainboard/intel/galileo/Makefile.inc | 2 ++ src/mainboard/intel/galileo/com_init.c | 26 ++++++++++++++++++++++++++ 3 files changed, 37 insertions(+) diff --git a/src/mainboard/intel/galileo/Kconfig b/src/mainboard/intel/galileo/Kconfig index dd2d1bb..6fe9abc 100755 --- a/src/mainboard/intel/galileo/Kconfig +++ b/src/mainboard/intel/galileo/Kconfig @@ -18,9 +18,18 @@ if BOARD_INTEL_GALILEO config BOARD_SPECIFIC_OPTIONS def_bool y select BOARD_ROMSIZE_KB_8192 + select ENABLE_BUILTIN_HSUART1 select PLATFORM_USES_FSP1_1 select SOC_INTEL_QUARK +config DCACHE_RAM_BASE + hex + default 0x80070000 + +config DCACHE_RAM_SIZE + hex + default 0x00008000 + if PLATFORM_USES_FSP1_1 config FSP_IMAGE_ID_STRING diff --git a/src/mainboard/intel/galileo/Makefile.inc b/src/mainboard/intel/galileo/Makefile.inc index 2c4be88..11010eb 100755 --- a/src/mainboard/intel/galileo/Makefile.inc +++ b/src/mainboard/intel/galileo/Makefile.inc @@ -15,6 +15,8 @@ CPPFLAGS_common += -I$(src)/vendorcode/intel/fsp/fsp1_1/quark +romstage-$(CONFIG_ENABLE_BUILTIN_HSUART1) += com_init.c + # Add the FSP binary to the cbfs image ifeq ($(CONFIG_HAVE_FSP_RAW_BIN),y) cbfs-files-y += fsp.bin diff --git a/src/mainboard/intel/galileo/com_init.c b/src/mainboard/intel/galileo/com_init.c new file mode 100644 index 0000000..3cf4cd6 --- /dev/null +++ b/src/mainboard/intel/galileo/com_init.c @@ -0,0 +1,26 @@ +/* + * This file is part of the coreboot project. + * + * Copyright (C) 2013 Google Inc. + * Copyright (C) 2015-2016 Intel Corp. + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; version 2 of the License. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
