On OMAP4, MMC2 controller has eMMC which draws power from VAUX regulator
on TWL. Though the eMMC supports dual voltage[1.8v/3v] as per ocr register,
its VCC is fixed at 3V for operation. With this once the mmc core selects
the minimum voltage[1.8] supported based on the ocr value read from OCR register,
eMMC will not get detected. Thus the platform data for MMC2 is updated with ocr
mask and same will be communicated to core which will set the regulator to
always operate at 3V when ever turned ON.

In OMAP4, as per new PM programming model, the legacy registers
which were there in OMAP3 are all shifted by 0x100 while new one's
are added from offset 0 to 0x10.
For OMAP4, the register offset appending of 0x100 done in devices.c
currently, is moved to driver file.This change fits in for current
implementation as well as once the driver undergoes hwmod adaptation.

Enable omap-serial driver in /mach-omap2/Kconfig and
move 8250 driver selection for zoom boards. With omap-serial
driver addition all omap-uarts can be handled with
omap-serial driver.
With addition of omap-serial driver console parameter
needs be changed in bootargs from ttyS* should be
replaced with ttyO* [O --> OMAP not ZERO]
For example: ttyS0[UART1 on 3430SDP] changes to ttyO0.
But with some boards that do not use omap-uart as console uart.
we need to handle them with 8250 driver. Ex: ZOOM2/3.
For zoom2/3 board we need to use 8250 serial driver and
console parameter will remain ttyS0 which basically uses
a Quad uart placed on the debug board connected through a
gpio line.

Convert UART core and PM support to use omap_device layer. Also add

- Remove all static platform_data setup and configuration. This is

When changing the L3 clock frequency, the CPU is executing from internal RAM
and the SDRC clock is disabled. During this time accesses made to external
DDR are stalled. If the ARM subsystem attempts to access the DDR while the
SDRC clock is disabled this will stall the CPU until the access to the SDRC
timeouts. A timeout on the SDRC should never occur. Once a timeout occurs all
the following accesses will be aborted and the DDR is no longer accessible.
Although the code being executed in the internal RAM does not directly access
the DDR, it was found that the branch prediction logic in the CPU may cause
the CPU to prefetch code from a DDR location while the SDRC clock is disabled.
This was causing an SDRC timeout which resulted in a system hang.
This patch fixes this problem by ensuring the branch prediction logic is
disabled while changing the L3 clock frequency. The branch prediction logic
is disabled by clearing the Z-bit in the ARM CTRL register.
Disabling the branch prediction logic does not have any noticable impact
on the execution time of this code section. The hardware observability
signals were used to monitor the sdrc idle time with and without this
patch when operating at different CPU frequencies (150MHz, 500MHz and
600MHz) and the total sdrc idle time when changing frequenct was in
the range of 9-11us. This was measured on an omap3430 SDP running the
omapzoom p-android-omap-2.6.29 branch.
