From 21cde8b83227fa324f246672b1e2d58408ea6bf8 Mon Sep 17 00:00:00 2001 From: Marc Jones Date: Sun, 7 May 2017 16:47:36 -0600 Subject: soc/amd/stoneyridge: Add CPU files Copy cpu/amd/pi/00670F00 to soc/amd/stoneyridge and soc/amd/common. This is the second patch in the process of converting Stoney Ridge to soc/. Changes: - update Kconfig and Makefiles - update vendorcode/amd for new soc/ path Change-Id: I8b6b1991372c2c6a02709777a73615a86e78ac26 Signed-off-by: Marc Jones Reviewed-on: https://review.coreboot.org/19723 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth --- src/soc/amd/common/Kconfig | 8 + src/soc/amd/common/Makefile.inc | 7 + src/soc/amd/common/amd_late_init.c | 40 ++++ src/soc/amd/common/cache_as_ram.inc | 170 +++++++++++++++++ src/soc/amd/common/heapmanager.c | 319 ++++++++++++++++++++++++++++++++ src/soc/amd/common/spi.c | 41 ++++ src/soc/amd/stoneyridge/Kconfig | 53 +++++- src/soc/amd/stoneyridge/Makefile.inc | 15 +- src/soc/amd/stoneyridge/acpi/cpu.asl | 78 ++++++++ src/soc/amd/stoneyridge/fixme.c | 97 ++++++++++ src/soc/amd/stoneyridge/model_15_init.c | 135 ++++++++++++++ 11 files changed, 958 insertions(+), 5 deletions(-) create mode 100644 src/soc/amd/common/amd_late_init.c create mode 100644 src/soc/amd/common/cache_as_ram.inc create mode 100644 src/soc/amd/common/heapmanager.c create mode 100644 src/soc/amd/common/spi.c create mode 100644 src/soc/amd/stoneyridge/acpi/cpu.asl create mode 100644 src/soc/amd/stoneyridge/fixme.c create mode 100644 src/soc/amd/stoneyridge/model_15_init.c (limited to 'src/soc') diff --git a/src/soc/amd/common/Kconfig b/src/soc/amd/common/Kconfig index fac3f43565..d4fe1f7523 100644 --- a/src/soc/amd/common/Kconfig +++ b/src/soc/amd/common/Kconfig @@ -2,3 +2,11 @@ config SOC_AMD_COMMON bool help common code for AMD SOCs + +if SOC_AMD_COMMON + +config SOC_AMD_PI + bool + default n + +endif # SOC_AMD_COMMON diff --git a/src/soc/amd/common/Makefile.inc b/src/soc/amd/common/Makefile.inc index 689065bd5a..1a4927efaa 100644 --- a/src/soc/amd/common/Makefile.inc +++ b/src/soc/amd/common/Makefile.inc @@ -1,5 +1,12 @@ ifeq ($(CONFIG_SOC_AMD_COMMON),y) +cpu_incs-y += $(src)/soc/amd/common/cache_as_ram.inc + +romstage-y += heapmanager.c + +ramstage-y += amd_late_init.c ramstage-y += amd_pci_util.c +ramstage-y += heapmanager.c +ramstage-$(CONFIG_SPI_FLASH) += spi.c endif diff --git a/src/soc/amd/common/amd_late_init.c b/src/soc/amd/common/amd_late_init.c new file mode 100644 index 0000000000..d9a5b43743 --- /dev/null +++ b/src/soc/amd/common/amd_late_init.c @@ -0,0 +1,40 @@ +/* + * This file is part of the coreboot project. + * + * Copyright (C) 2012 Advanced Micro Devices, Inc. + * + * 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.
