Chris Metcalf bdb8205455 tile: remove DEBUG_EXTRA_FLAGS kernel config option

It isn't used any more by us now that the generic kernel build
offers DEBUG_INFO_REDUCED, so just get rid of it.

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

If building with TILERA_ROOT set (i.e. using the Tilera Multicore

Development Environment) we can set CROSS_COMPILE based on that.

If we're not cross-compiling, make sure we're on the right architecture.

Only bother to test for a few common targets, to avoid useless errors.

ifeq ($(CROSS_COMPILE),) ifdef TILERA_ROOT CROSS_COMPILE := $(TILERA_ROOT)/bin/tile- else goals := $(if $(MAKECMDGOALS), $(MAKECMDGOALS), all) ifneq ($(strip $(filter vmlinux modules all,$(goals))),) HOST_ARCH := $(shell uname -m) ifneq ($(HOST_ARCH),$(ARCH)) $(error Set TILERA_ROOT or CROSS_COMPILE when building $(ARCH) on $(HOST_ARCH)) endif endif endif endif

The tile compiler may emit .eh_frame information for backtracing.

In kernel modules, this causes load failures due to unsupported relocations.

KBUILD_CFLAGS += -fno-asynchronous-unwind-tables

LIBGCC_PATH :=
$(shell $(CC) $(KBUILD_CFLAGS) $(KCFLAGS) -print-libgcc-file-name)

Provide the path to use for "make defconfig".

We default to the newer TILE-Gx architecture if only "tile" is given.

ifeq ($(ARCH),tile) KBUILD_DEFCONFIG := tilegx_defconfig else KBUILD_DEFCONFIG := $(ARCH)_defconfig endif

Used as a file extension when useful, e.g. head_$(BITS).o

Not needed for (e.g.) "$(CC) -m32" since the compiler automatically

uses the right default anyway.

export BITS ifeq ($(CONFIG_TILEGX),y) BITS := 64 else BITS := 32 endif

head-y := arch/tile/kernel/head_$(BITS).o

libs-y += arch/tile/lib/ libs-y += $(LIBGCC_PATH)

See arch/tile/Kbuild for content of core part of the kernel

core-y += arch/tile/

core-$(CONFIG_TILE_GXIO) += arch/tile/gxio/

ifdef TILERA_ROOT INSTALL_PATH ?= $(TILERA_ROOT)/tile/boot endif
