Masahiro Yamada a4954fd772 kbuild: remove obj-n and lib-n handling
Kconfig never defines CONFIG_* as 'n'.
Now obj-n is only used in firmware/Makefile and it can be
replaced with obj-.  No makefile uses lib-n.

Let's rip off obj-n and lib-n.

kbuild file for firmware/

Create $(fwabs) from $(CONFIG_EXTRA_FIRMWARE_DIR) -- if it doesn't have a

leading /, it's relative to $(srctree).

fwdir := $(subst $(quote),,$(CONFIG_EXTRA_FIRMWARE_DIR)) fwabs := $(addprefix $(srctree)/,$(filter-out /%,$(fwdir)))$(filter /%,$(fwdir))

fw-external-y := $(subst $(quote),,$(CONFIG_EXTRA_FIRMWARE))

There are three cases to care about:

1. Building kernel with CONFIG_FIRMWARE_IN_KERNEL=y -- $(fw-shipped-y) should

include the firmware files to include, according to .config

2. 'make modules_install', which will install firmware for modules, and

also for the in-kernel drivers when CONFIG_FIRMWARE_IN_KERNEL=n

3. 'make firmware_install', which installs all firmware, unconditionally.

For the former two cases we want $(fw-shipped-y) and $(fw-shipped-m) to be

accurate. In the latter case it doesn't matter -- it'll use $(fw-shipped-all).

But be aware that the config file might not be included at all.

One of these files will change, or come into existence, whenever

the configuration changes between 32-bit and 64-bit. The .S files

need to change when that happens.

wordsize_deps := $(wildcard include/config/64bit.h include/config/32bit.h
include/config/ppc32.h include/config/ppc64.h
include/config/superh32.h include/config/superh64.h

include/config/extra/firmware/dir.h $(call cmd,fwbin,$(fwabs)/$(patsubst $(obj)/%.gen.S,%,$@))

The .o files depend on the binaries directly; the .S files don't.

$(patsubst %,$(obj)/%.gen.o, $(fw-shipped-y)): %.gen.o: % $(patsubst %,$(obj)/%.gen.o, $(fw-external-y)): $(obj)/%.gen.o: $(fwdir)/%

.ihex is used just as a simple way to hold binary files in a source tree

where binaries are frowned upon. They are directly converted with objcopy.

$(obj)/%: $(obj)/%.ihex $(call cmd,ihex)

Don't depend on ihex2fw if we're installing and it already exists.

Putting it after | in the dependencies doesn't seem sufficient when

we're installing after a cross-compile, because ihex2fw has dependencies

on stuff like /usr/lib/gcc/ppc64-redhat-linux/4.3.0/include/stddef.h and

thus wants to be rebuilt. Which it can't be, if the prebuilt kernel tree

is exported read-only for someone to run 'make install'.

ifeq ($(INSTALL):$(wildcard $(obj)/ihex2fw),install:$(obj)/ihex2fw) ihex2fw_dep := else ihex2fw_dep := $(obj)/ihex2fw endif

.HEX is also Intel HEX, but where the offset and length in each record

is actually meaningful, because the firmware has to be loaded in a certain

order rather than as a single binary blob. Thus, we convert them into our

more compact binary representation of ihex records (<linux/ihex.h>)

$(obj)/%.fw: $(obj)/%.HEX $(ihex2fw_dep) $(call cmd,ihex2fw)

.H16 is our own modified form of Intel HEX, with 16-bit length for records.

$(obj)/%.fw: $(obj)/%.H16 $(ihex2fw_dep) $(call cmd,h16tofw)

obj-y += $(patsubst %,%.gen.o, $(fw-external-y)) obj-$(CONFIG_FIRMWARE_IN_KERNEL) += $(patsubst %,%.gen.o, $(fw-shipped-y))

ifeq ($(KBUILD_SRC),)

Makefile.build only creates subdirectories for O= builds, but external

firmware might live outside the kernel source tree

_dummy := $(foreach d,$(addprefix $(obj)/,$(dir $(fw-external-y))), $(shell [ -d $(d) ] || mkdir -p $(d))) endif

Remove .S files and binaries created from ihex

(during 'make clean' .config isn't included so they're all in $(fw-shipped-))

targets := $(fw-shipped-) $(patsubst $(obj)/%,%,
$(shell find $(obj) -name *.gen.S 2>/dev/null))

Without this, built-in.o won't be created when it's empty, and the

final vmlinux link will fail.
