This file is included by the global makefile so that you can add your own

architecture-specific flags and dependencies. Remember to do have actions

for "archclean" and "archdep" for cleaning up and making dependencies for

this architecture

arch_dir = arch/v850

CFLAGS += -mv850e

r16 is a fixed pointer to the current task

CFLAGS += -ffixed-r16 -mno-prolog-function CFLAGS += -fno-builtin CFLAGS += -D__linux__ -DUTS_SYSNAME="uClinux"

By default, build a kernel that runs on the gdb v850 simulator.

KBUILD_DEFCONFIG := sim_defconfig

This prevents the linker from consolidating the .gnu.linkonce.this_module

section into .text (which the v850 default linker script for -r does for

some reason)

LDFLAGS_MODULE += --unique=.gnu.linkonce.this_module

OBJCOPY_FLAGS_BLOB := -I binary -O elf32-little -B v850e

head-y := $(arch_dir)/kernel/head.o $(arch_dir)/kernel/init_task.o core-y += $(arch_dir)/kernel/ libs-y += $(arch_dir)/lib/

Deal with the initial contents of the root device

ifdef ROOT_FS_IMAGE core-y += root_fs_image.o

Because the kernel build-system erases all explicit .o build rules, we

have to use an intermediate target to fool it into building for us.

This results in it being built anew each time, but that's alright.

root_fs_image.o: root_fs_image_force

root_fs_image_force: $(ROOT_FS_IMAGE) $(OBJCOPY) $(OBJCOPY_FLAGS_BLOB) --rename-section .data=.root,alloc,load,readonly,data,contents $< root_fs_image.o endif

CLEAN_FILES += root_fs_image.o
