Rename obj to coreinfo_obj so it doesn't conflict with the obj variable in libpayload. - Change $(shell pwd) to $(CURDIR) to find the directory without going to the shell - Fix libpayloaddir so it doesn't get installed to libpayload/libpayload - Make all relative paths absolute by prepending $(src) - Remove .xcompile when doing a clean Change-Id: I2ffb06a87e30a5eeff5b0dfc0ba62b5e9ab46e26 Signed-off-by: Martin Roth <martinroth(a)google.com> --- payloads/coreinfo/Makefile | 50 +++++++++++++++++++++++----------------------- 1 file changed, 25 insertions(+), 25 deletions(-) diff --git a/payloads/coreinfo/Makefile b/payloads/coreinfo/Makefile index c9f5c10..750402b 100644 --- a/payloads/coreinfo/Makefile +++ b/payloads/coreinfo/Makefile @@ -14,18 +14,18 @@ ## GNU General Public License for more details. ## -src := $(shell pwd) +src := $(CURDIR) srctree := $(src) srck := $(src)/../../util/kconfig -obj := $(src)/build +coreinfo_obj := $(src)/build objk := $(src)/build/util/kconfig export KERNELVERSION := 0.1.0 -export KCONFIG_AUTOHEADER := $(obj)/config.h -export KCONFIG_AUTOCONFIG := $(obj)/auto.conf -export KCONFIG_DEPENDENCIES := $(obj)/auto.conf.cmd -export KCONFIG_SPLITCONFIG := $(obj)/config -export KCONFIG_TRISTATE := $(obj)/tristate.conf +export KCONFIG_AUTOHEADER := $(coreinfo_obj)/config.h +export KCONFIG_AUTOCONFIG := $(coreinfo_obj)/auto.conf +export KCONFIG_DEPENDENCIES := $(coreinfo_obj)/auto.conf.cmd +export KCONFIG_SPLITCONFIG := $(coreinfo_obj)/config +export KCONFIG_TRISTATE := $(coreinfo_obj)/tristate.conf export KCONFIG_NEGATIVES := 1 export Kconfig := Kconfig @@ -47,25 +47,25 @@ HOSTCXX ?= g++ HOSTCFLAGS := -I$(srck) -I$(objk) HOSTCXXFLAGS := -I$(srck) -I$(objk) -LIBCONFIG_PATH := ../libpayload -LIBPAYLOAD_DIR := build/libpayload -HAVE_LIBPAYLOAD := $(wildcard $(LIBPAYLOAD_DIR)/libpayload/lib/libpayload.a) +LIBCONFIG_PATH := $(src)/../libpayload +LIBPAYLOAD_DIR := $(coreinfo_obj)/libpayload +HAVE_LIBPAYLOAD := $(wildcard $(LIBPAYLOAD_DIR)/lib/libpayload.a) LIB_CONFIG ?= defconfig OBJCOPY ?= objcopy -INCLUDES = -I$(obj) -include $(LIBPAYLOAD_DIR)/libpayload/include/kconfig.h +INCLUDES = -I$(coreinfo_obj) -include $(LIBPAYLOAD_DIR)/include/kconfig.h OBJECTS = cpuinfo_module.o cpuid.S.o pci_module.o coreboot_module.o \ nvram_module.o bootlog_module.o ramdump_module.o lar_module.o \ multiboot_module.o cbfs_module.o coreinfo.o -OBJS = $(patsubst %,$(obj)/%,$(OBJECTS)) -TARGET = $(obj)/coreinfo.elf +OBJS = $(patsubst %,$(coreinfo_obj)/%,$(OBJECTS)) +TARGET = $(coreinfo_obj)/coreinfo.elf all: real-all # in addition to the dependency below, create the file if it doesn't exist # to silence warnings about a file that would be generated anyway. -$(if $(wildcard .xcompile),,$(eval $(shell ../../util/xcompile/xcompile $(XGCCPATH) > .xcompile || rm -f .xcompile))) -.xcompile: ../../util/xcompile/xcompile +$(if $(wildcard .xcompile),,$(eval $(shell $(src)/../../util/xcompile/xcompile $(XGCCPATH) > .xcompile || rm -f .xcompile))) +.xcompile: $(src)/../../util/xcompile/xcompile $< $(XGCCPATH) > $@.tmp \mv -f $@.tmp $@ 2> /dev/null || rm -f $@.tmp $@ @@ -78,8 +78,8 @@ CC := $(CC_$(ARCH-y)) AS := $(AS_$(ARCH-y)) OBJCOPY := $(OBJCOPY_$(ARCH-y)) -LPCC := CC="$(CC)" $(LIBPAYLOAD_DIR)/libpayload/bin/lpgcc -LPAS := AS="$(AS)" $(LIBPAYLOAD_DIR)/libpayload/bin/lpas +LPCC := CC="$(CC)" $(LIBPAYLOAD_DIR)/bin/lpgcc +LPAS := AS="$(AS)" $(LIBPAYLOAD_DIR)/bin/lpas CFLAGS += -Wall -Werror -Os -fno-builtin $(CFLAGS_$(ARCH-y)) $(INCLUDES) @@ -87,18 +87,18 @@ ifneq ($(strip $(HAVE_DOTCONFIG)),) include $(src)/.config real-all: $(TARGET) -$(TARGET): $(src)/.config $(obj)/config.h $(OBJS) libpayload +$(TARGET): $(src)/.config $(coreinfo_obj)/config.h $(OBJS) libpayload printf " LPCC $(subst $(shell pwd)/,,$(@)) (LINK)\n" $(LPCC) -o $@ $(OBJS) $(OBJCOPY) --only-keep-debug $@ $(TARGET).debug $(OBJCOPY) --strip-debug $@ $(OBJCOPY) --add-gnu-debuglink=$(TARGET).debug $@ -$(obj)/%.S.o: $(src)/%.S libpayload +$(coreinfo_obj)/%.S.o: $(src)/%.S libpayload printf " LPAS $(subst $(shell pwd)/,,$(@))\n" $(LPAS) -o $@ $< -$(obj)/%.o: $(src)/%.c libpayload +$(coreinfo_obj)/%.o: $(src)/%.c libpayload printf " LPCC $(subst $(shell pwd)/,,$(@))\n" $(LPCC) $(CFLAGS) -c -o $@ $< @@ -116,18 +116,18 @@ libpayload: else libpayload: printf "Building libpayload @ $(LIBCONFIG_PATH).\n" -

Patch set updated for coreboot: soc/intel/apollolake: Add support for memory-mapped boot media
by Andrey Petrov 07 Mar '16

07 Mar '16

Andrey Petrov (andrey.petrov(a)intel.com) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/13706 -gerrit commit 67c0b06219e4fd3d6380572bbe87c4f12333d148 Author: Andrey Petrov <andrey.petrov(a)intel.com> Date: Fri Feb 12 15:12:43 2016 -0800 soc/intel/apollolake: Add support for memory-mapped boot media On Apollo Lake SPI flash is memory mapped. The mapping is different to previous platforms. Only "BIOS" region is mapped in contrast to whole flash. Also, the 128 KiB right below 4 GiB are being decoded by readonly SRAM. Fail accesses to those regions, rather than returning false data.
