If the board has a debug uart the user is given a choice of which
uart to use. The user can also select NONE, which means not to use one.
In most of our header files when NONE is selected nothing is defined
for MSM_DEBUG_UART_PHYS or MSM_DEBUG_UART_BASE. This causes a compile
failure in debug-macro.S which expect something to be defined there.

Example of the failure,

arch/arm/kernel/built-in.o: In function `hexbuf':
linux-2.6/arch/arm/kernel/debug.S:186: undefined reference to `MSM_DEBUG_UART_PHYS'
linux-2.6/arch/arm/kernel/debug.S:186: undefined reference to `MSM_DEBUG_UART_BASE'

This fixes the compile failure by adding an ifdef to debug-macro.S
that removes all the debug uart code in the case of NONE.
Signed-off-by: NDaniel Walker <dwalker@codeaurora.org>

Originally there was an ifdef case to handle when no debug uart
was selected. In commit 0ea12930
that case was removed which causes the following build failure,

linux-2.6/arch/arm/kernel/debug.S: Assembler messages:
linux-2.6/arch/arm/kernel/debug.S:174: Error: bad instruction `addruart r1,r2'
linux-2.6/arch/arm/kernel/debug.S:176: Error: bad instruction `waituart r2,r3'

linux-2.6/arch/arm/kernel/debug.S:190: Error: bad instruction `addruart r1,r2'

This is a partial revert to add back the case which was removed with
two caveats. First the API for the addruart macro was updated, and
the new addruart case now return 0xfff00000 so that a know IO mapping
is created instead of a random one.

Adding card detect callback function and card detect configuration
function for MMC1 Controller on OMAP4.

Card detect configuration function does initial configuration of the
MMC Control & PullUp-PullDown registers of Phoenix.

For MMC1 Controller, card detect interrupt source is
twl6030 which is non-gpio. The card detect call back function provides
card present/absent status by reading MMC Control register present
on twl6030.

Since OMAP4 doesn't use any GPIO line as used in OMAP3 for card detect,
the suspend/resume initialization which was done in omap_hsmmc_gpio_init
previously is moved to the probe thus making it generic for both OMAP3 &
OMAP4.

On AP4EVB the card detect pin of the top SD/MMC slot is not directly
connected to the tmio/mmcif controller but to a GPIO pin, so polling
needs to be done for SDHI1 and MMCIF in order to support hotplug for
that slot. SHDI1 and MMCIF share that slot, and the used controller
is selected by a DIP switch.
This patch adds a helper function to check if a card is present in that
particular slot, registers this function with SDHI1 and MMCIF and enables
polling for SDHI1.

Use memblock information to setup lowmem mappings rather than the
membank array.

This allows platforms to manipulate the memblock information during
initialization to reserve (and remove) memory from the kernel's view
of memory - and thus allowing platforms to setup their own private
mappings for this memory without causing problems with multiple
aliasing mappings:

	size = min(size, SZ_2M);
	base = memblock_alloc(size, min(align, SZ_2M));
	memblock_free(base, size);
	memblock_remove(base, size);

This is needed because multiple mappings of regions with differing
attributes (sharability, type, cache) are not permitted with ARMv6
and above.
