Masahiro Yamada 9319f4539c kbuild: support simultaneous "make %config" and "make all"

Kbuild is supposed to support mixed targets. (%config and build targets)

But "make all" did nothing if it was run with configuration targets.
For example,

  $ LANG=C make defconfig all
    HOSTCC  scripts/basic/fixdep
    HOSTCC  scripts/kconfig/conf.o
    SHIPPED scripts/kconfig/zconf.tab.c
    SHIPPED scripts/kconfig/zconf.lex.c
    SHIPPED scripts/kconfig/zconf.hash.c
    HOSTCC  scripts/kconfig/zconf.tab.o
    HOSTLD  scripts/kconfig/conf
  *** Default configuration is based on 'x86_64_defconfig'
  #
  # configuration written to .config
  #
  make: Nothing to be done for `all'.

This commits allows "make %config all" and makes sure
mixed targets are built one by one in the given order.

#!/bin/sh

Generates a small Makefile used in the root of the output

directory, to allow make to be started from there.

The Makefile also allow for more convinient build of external modules

Usage

$1 - Kernel src directory

$2 - Output directory

$3 - version

$4 - patchlevel

test ! -r $2/Makefile -o -O $2/Makefile || exit 0

Only overwrite automatically generated Makefiles

(so we do not overwrite kernel Makefile)

if test -e $2/Makefile && ! grep -q Automatically $2/Makefile then exit 0 fi if [ "${quiet}" != "silent_" ]; then echo " GEN $2/Makefile" fi

cat << EOF > $2/Makefile

Automatically generated by $0: don't edit

VERSION = $3 PATCHLEVEL = $4

lastword = $(word $(words $(1)),$(1)) makedir := $(dir $(call lastword,$(MAKEFILE_LIST)))

ifeq ("$(origin V)", "command line") VERBOSE := $(V) endif ifneq ($(VERBOSE),1) Q := @ endif

MAKEARGS := -C $1 MAKEARGS += O=$(if $(patsubst /%,,$(makedir)),$(CURDIR)/)$(patsubst %/,%,$(makedir))

MAKEFLAGS += --no-print-directory

.PHONY: __sub-make $(MAKECMDGOALS)

__sub-make: $(Q)$(MAKE) $(MAKEARGS) $(MAKECMDGOALS)

$(filter-out __sub-make, $(MAKECMDGOALS)): __sub-make @: EOF
