The mach/dm365.h and mach/dm646xh headers are currently being included
in some device drivers. The removal of those includes is already merged
in some subsystem trees, but adding the dummy files ensures that this

There are instances of IO_ADDRESS() being used for system module
(sysmod) register access. Eliminate this in favor of a ioremap()
based access. ioremap() the entire sysmod address space once during
boot-up and provide a helper macro to access specific register
offsets within the address space.
With this, also eliminate ioremap() of specific sysmodule registers
related to VPIF happening in DM646x EVM code.
While at it, also eliminate some duplicate sysmod register offset macros
defined in code and place offset definitions at one place in davinci.h

Remove individual platform header files for dm365, dm355, dm644x
and dm646x and consolidate it into a single and common
header file davinci.h placed in arch/arm/mach-davinci.
This reduces the pollution in the include/mach and is consistent
with Russell's suggestions as part of his "pet peaves" mail.
(See #4 in: http://lists.infradead.org/pipermail/linux-arm-kernel/2011-November/071516.html)
While at it, fix the forward declaration of spi_board_info,
and include the right header file instead.

no longer does anything useful.
For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions. As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove

Some platforms (like OMAP not to name it) are doing rather complicated

Some devices connected to the MMC bus are power controlled by external
means. For instance, an SDIO device may be powered down/up by an
external gpio line.
In order to avoid toggling power from within the MMC host driver, add a
set_power callback function, which will be called by set_ios upon
powering down/up.

Recall the recently added prefix requirements:
* "NAND_" for flags in nand.h, used in nand_chip.options
* "NAND_BBT_" for flags in bbm.h, used in nand_chip.bbt_options
or in nand_bbt_descr.options
Thus, I am changing NAND_USE_FLASH_BBT to NAND_BBT_USE_FLASH.
Again, this flag is found in bbm.h and so should NOT be used in the
"nand_chip.options" field.

This patch works with the following three flags from two headers (nand.h
and bbm.h):
(1) NAND_USE_FLASH_BBT (nand.h)
(2) NAND_USE_FLASH_BBT_NO_OOB (nand.h)
(3) NAND_BBT_NO_OOB (bbm.h)
These flags are all related and interdependent, yet they were in
different headers. Flag (2) is simply the combination of (1) and (3) and
can be eliminated.
This patch accomplishes the following:
* eliminate NAND_USE_FLASH_BBT_NO_OOB (i.e., flag (2))
* move NAND_USE_FLASH_BBT (i.e., flag (1)) to bbm.h
It's important to note that because (1) and (3) are now both found in
bbm.h, they should NOT be used in the "nand_chip.options" field.
I removed a small section from the mtdnand DocBook because it referes to
NAND_USE_FLASH_BBT in nand.h, which has been moved to bbm.h.

Rather than marking the mach/gpio.h header files which want to use the
trivial GPIOLIB implementation, mark those which do not want to use it
instead. This means that by default, you get the trivial implementation
and only have to do something extra if you need to. This should
encourage the use of the trivial default implementation.
As an additional bonus, several gpio.h header files become empty.
