2c15513010 OMAP3 Move twl4030 power and led functions
Because twl4030 now has its own device files, move exiting
omap3 power_init_r to a new location.

power_init_r is the only function in board/omap3/common.
It initializes the twl4030 power for the board and enables
the led.

The power part of the the function is moved to twl4030_power_init in
drivers/power/twl4030.c The power compilation is conditional on the
existing config variable CONFIG_TWL4030_POWER.

The led part is moved to twl4030_led_init in the new file
drivers/misc/twl4030_led.c  The led compilation is conditional on
the new config variable CONFIG_TWL4030_LED

The directory board/omap3/common was removed because power_init_r
was the only function in it.

cd7826359e TWL4030 Add power reset button
The Zoom2 power reset button is on the top right side of the
main board.  Press and hold for about to 8 seconds to completely
reset the board.

Some of the beta boards have a hardware problem that prevents
using this feature.  If is difficult to further characterize the
boards that fail.  So disable resetting for all beta boards.

The Zoom1 reset button is the red circle on the top right,
front of the board.  Press and hold the button for 8 seconds to
completely reset the board.

After analyzing beagle, it was determined that other boards
that use the twl4030 for power managment can also make use
this function.

The resetting is done by the power management part of the twl4030.
Since there is no existing drivers/power, add one.

The compilation of power/twl4030.h is controlled by the config
variable CONFIG_TWL4030_POWER

a30f519bd0 ZOOM2 detect the version of the zoom2 board at runtime.
There are currently 3 versions of the zoom2 board.
The production board, that is currently being released.
The beta board, similar in form to the production board but not released.
The alpha board, a set of PCBs with a very limited circulation.

GPIO 94 is used to determine the version of the board. If GPIO 94 is clear,
the board is a production board, otherwise it is a beta board.

The alpha board will likely be mistaken for a beta board.  An alpha board
was unavailible for testing.

This has been tested on the beta and production boards.

660888b7fb ZOOM2 Add serial support.
Zoom2 serial is in general supplied by one of the 4 UARTS on the debug board.
The default serial is from the USB connector on left side of the debug board.
The USB connector will produce 2 of the 4 UARTS.  On your host pick the first
enumeration.

The details of the setting of the serial gpmc setup are not available.
The values were provided by another party.

The serial port set up is the same with Zoom1.
Baud rate 115200, 8 bit data, no parity, 1 stop bit, no flow.

The kernel bootargs are
console=ttyS3,115200n8

This patch provides a zoom2 base target by copying zoom1 and by making some
obvious changes.

To configure, run
make omap3_zoom2_config
