[PATCH] m32r: Support M3A-2170(Mappi-III) platform
This patchset is for supporting a new m32r platform, M3A-2170(Mappi-III)
evaluation board. An M32R chip multiprocessor is equipped on the board.
http://http://www.linux-m32r.org/eng/platform/platform.html
* arch/m32r/Kconfig: Support Mappi-III platform.
* arch/m32r/kernel/Makefile: ditto.
* arch/m32r/kernel/io_mappi3.c: ditto.
* arch/m32r/kernel/setup.c: ditto.
* arch/m32r/kernel/setup_mappi3.c: ditto.
* include/asm-m32r/m32102.h: ditto.
* include/asm-m32r/m32r.h: ditto.
* include/asm-m32r/mappi3/mappi3_pld.h: ditto.
* include/asm-m32r/ide.h: CF support for Mappi-III.
* arch/m32r/kernel/setup_mappi3.c: ditto.
* arch/m32r/mappi3/defconfig.smp: A default config file for Mappi-III.
* arch/m32r/mappi3/dot.gdbinit: A default .gdbinit file for Mappi-III.
* arch/m32r/boot/compressed/m32r_sio.c: Modified for Mappi-III
- At boot time, m32r-g00ff bootloader makes MMU off for Mappi-III,
on the contrary it makes MMU on for Mappi-II.
* arch/m32r/kernel/io_mappi2.c: Update comments.
* arch/m32r/kernel/setup_mappi2.c: ditto.
