dm: select CONFIG_DM* options As mentioned in the previous commit, adding default values in each Kconfig causes problems because it does not co-exist with the "depends on" syntax. (Please note this is not a bug of Kconfig.) We should not do so unless we have a special reason. Actually, for CONFIG_DM*, we have no good reason to do so. Generally, CONFIG_DM is not a user-configurable option. Once we convert a driver into Driver Model, the board only works with Driver Model, i.e. CONFIG_DM must be always enabled for that board. So, using "select DM" is more suitable rather than allowing users to modify it. Another good thing is, Kconfig warns unmet dependencies for "select" syntax, so we easily notice bugs. Actually, CONFIG_DM and other related options have been added without consistency: some into arch/*/Kconfig, some into board/*/Kconfig, and some into configs/*_defconfig. This commit prefers "select" and cleans up the following issues. [1] Never use "CONFIG_DM=n" in defconfig files It is really rare to add "CONFIG_FOO=n" to disable CONFIG options. It is more common to use "# CONFIG_FOO is not set". But here, we do not even have to do it. Less than half of OMAP3 boards have been converted to Driver Model. Adding the default values to arch/arm/cpu/armv7/omap3/Kconfig is weird. Instead, add "select DM" only to appropriate boards, which eventually eliminates "CONFIG_DM=n", etc. [2] Delete redundant CONFIGs Sandbox sets CONFIG_DM in arch/sandbox/Kconfig and defines it again in configs/sandbox_defconfig. Likewise, OMAP3 sets CONFIG_DM arch/arm/cpu/armv7/omap3/Kconfig and defines it also in omap3_beagle_defconfig and devkit8000_defconfig. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

config SYS_ARCH
string
help
This option should contain the architecture name to build the
appropriate arch/<CONFIG_SYS_ARCH> directory.
All the architectures should specify this option correctly.
config SYS_CPU
string
help
This option should contain the CPU name to build the correct
arch/<CONFIG_SYS_ARCH>/cpu/<CONFIG_SYS_CPU> directory.
This is optional. For those targets without the CPU directory,
leave this option empty.
config SYS_SOC
string
help
This option should contain the SoC name to build the directory
arch/<CONFIG_SYS_ARCH>/cpu/<CONFIG_SYS_CPU>/<CONFIG_SYS_SOC>.
This is optional. For those targets without the SoC directory,
leave this option empty.
config SYS_VENDOR
string
help
This option should contain the vendor name of the target board.
If it is set and
board/<CONFIG_SYS_VENDOR>/common/Makefile exists, the vendor common
directory is compiled.
If CONFIG_SYS_BOARD is also set, the sources under
board/<CONFIG_SYS_VENDOR>/<CONFIG_SYS_BOARD> directory are compiled.
This is optional. For those targets without the vendor directory,
leave this option empty.
config SYS_BOARD
string
help
This option should contain the name of the target board.
If it is set, either board/<CONFIG_SYS_VENDOR>/<CONFIG_SYS_BOARD>
or board/<CONFIG_SYS_BOARD> directory is compiled depending on
whether CONFIG_SYS_VENDOR is set or not.
This is optional. For those targets without the board directory,
leave this option empty.
config SYS_CONFIG_NAME
string
help
This option should contain the base name of board header file.
The header file include/configs/<CONFIG_SYS_CONFIG_NAME>.h
should be included from include/config.h.
