U-Boot has compelled all boards to have
board/${BOARD}/ or board/${VENDOR}/${BOARD}/ directory.Sometimes it does not seem suitable for some boards,
for example Sandbox. (Is it a board?)And arcangel4 board has nothing to compile
under the board directory.This commit makes the build system more flexible:
If '' is given to the 6th column (=Board name) of boards.cfg,
Kbuild will not descend into the board directory.Signed-off-by: Masahiro Yamada

Programs in tools/ directory are usually built for the host.
But some of them (mkimage, dumpimge, gen_eth_addr, etc.) are
useful on the target OS too.Actually, prior to Kbuild, U-Boot could build tools for
the target like follows:$ make _config
$ export CROSS_COMPILE=
$ make HOSTCC=${CROSS_COMPILE}gcc HOSTSTRIP=${CROSS_COMPILE}strip toolsIn Kbuild, we can no longer replace HOSTCC at the command line.
In order to get back that feature, this commit adds "cross-tools" target.
Usage:
Build tools for the host
$ make CROSS_COMPILE= toolsBuild tools for the target
$ make CROSS_COMPILE= cross_toolsBesides, "make cross_tools" strip tools programs because we
generally expect smaller storages on embedded systems.Signed-off-by: Masahiro Yamada

As an example of how to write a uclass and a driver, provide a demo version
of each, accessible through the 'demo' command.To use these with driver model, define CONFIG_CMD_DEMO and CONFIG_DM_DEMO.
The two demo drivers are enabled with CONFIG_DM_DEMO_SIMPLE and
CONFIG_DM_DEMO_SHAPE.Signed-off-by: Simon Glass

Add some tests of driver model functionality. Coverage includes:
- basic init
- binding of drivers to devices using platform_data
- automatic probing of devices when referenced
- availability of platform data to devices
- lifecycle from bind to probe to remove to unbind
- renumbering within a uclass when devices are probed/removed
- calling driver-defined operations
- deactivation of drivers when removed
- memory leak across creation and destruction of drivers/uclasses
- uclass init/destroy methods
- automatic probe/remove of children/parents when neededThis function is enabled for sandbox, using CONFIG_DM_TEST.

Add driver model functionality for generic board.
This includes data structures and base code for registering devices and
uclasses (groups of devices with the same purpose, e.g. all I2C ports will
be in the same uclass).The feature is enabled with CONFIG_DM.

Add support for building a device tree for sandbox's CONFIG_OF_HOSTFILE
option to make it easier to use device tree with sandbox.This adjusts the Makefile to build a u-boot.dtb file which can be passed
to sandbox U-Boot with:./u-boot -d u-boot.dtb

Now we have two different frameworks for doing the same thing.
I'd like to propose to drop nand_spl framework.
How about deleting it before v2014.07 release?In the interim, this commit will display a warning message
when compiling nand_spl board.Now we have 19 nand_spl boards:
MPC8315ERDB_NAND
SIMPC8313_LP
SIMPC8313_SP
MPC8536DS_NAND
MPC8569MDS_NAND
MPC8572DS_NAND
P1023RDS_NAND

P2020RDB_NAND
acadia_nand

Same as the previous commit.
Move sanity check to prepare1 target to avoid nasty troubles.Before this commit, LDSCRIPT existence was not checked
when it was specified by CONFIG_SYS_LDSCRIPT.
Now LDSCRIPT existence is checked for all boards.$(wildcard $(LDSCRIPT)) must point to the linker scripts
with absolute path.
Otherwise, make will terminate with a false error
on out-of-tree build.Signed-off-by: Masahiro Yamada

Before this commit, make terminated with an error
where is shouldn't under some condition.This bug happened when we built a board unsupporting
generic board right after building with generic board.For example, the following sequence failed.
(harmony uses generic board but microblaze-generic does not
support it)$ make harmony_config
Configuring for harmony board...
$ make CROSS_COMPILE=arm-linux-gnueabi-
[ Build succeed ]
$ make microblaze-generic_config
Configuring for microblaze-generic board...
$ make CROSS_COMPILE=microblaze-linux-
Makefile:488: *** Your architecture does not support generic board.
Please undefined CONFIG_SYS_GENERIC_BOARD in your board config file. Stop.We had to do "make clean" before building the microblaze board.
This commit fixes this unconvenience.

which is run after generation of include/autoconf.mk.Signed-off-by: Masahiro Yamada

Commit 6ab6b2af deleted ./u-boot.dtb because it was a copy
of dts/dt.dtb.But Simon suggested to keep u-boot.dtb at the top directory
because it is a build output.After discussions, we agreed on revival of ./u-boot.dtb.

Generate include/generated/generic-asm-offsets.h and
include/generated/asm-offsets.h in ./Kbuild.This commit also changes the include guard.
Before this commit, __ASM_OFFSETS_H__ was used for both of them.
So we could not include generic-asm-offsets.h and asm-offsets.h
at the same time.This commit renames the include guard of the former to
__GENERIC_ASM_OFFSETS_H__.Signed-off-by: Masahiro Yamada

- Generate include/generated/{timestamp.h, version.h}
more simply by using filechk rule.- Add $(UBOOTRELEASE) variable and re-write u-boot.imx rule
more simply.- Rename U_BOOT_VERSION in Makefile to UBOOTVERSION
Before this commit, the same variable name, "U_BOOT_VERSION"
was used for two different strings.One of them was defined in Makefile.
It takes the form like "2014.01-rc1" and used in
makefiles and script files.The other is defined in include/generated/version.h
It takes the form like "U-Boot 2014.01-rc1-00010-gbe6d426-dirty"
and used in C and Aseembler.It is confusing when grepping the source tree. So, this commit
renames the former to UBOOTVERSION.Signed-off-by: Masahiro Yamada

Conflicts:
Makefile
drivers/net/npe/MakefileThese two conflicts arise from commit 0b2d3f20
("ARM: NET: Remove the IXP NPE ethernet driver") and are
resolved by deleting the drivers/net/npe/Makefile file
and removing the CONFIG_IXP4XX_NPE line from Makefile. -

This commit fixes two problems:
[1] We could not do board configuration and "make all"
in one command line.For example, the following did not work as we expect:
$ make sandbox_config all
Configuring for sandbox board...
make: Nothing to be done for `all'.[2] mixed-target build did not work with -j option
For example, the following did not work:
$ make -j8 sandbox_config u-boot
Makefile:481: *** "System not configured - see README". Stop.
make: *** [u-boot] Error 2
make: *** Waiting for unfinished jobs....
Configuring for sandbox board...Going forward, we can do
$ make -j8 sandbox_config allThis is the same as
$ make sandbox_config
$ make -j8Signed-off-by: Masahiro Yamada

This commit refactors cleaning targets such as
clean, clobber, mrpropper, distclean

$(MTD_VERSION) is used in tools/env/Makefile
If you specify a variable at a command line like:
$ make MTD_VERSION=old env
or specify it thru an envrionment variable like:
$ export MTD_VERSION=old
$ make env
it is inherited to the sub-make too.
We do not need to pass it from the top Makefile explicitely.Signed-off-by: Masahiro Yamada
