New u-boot command for status of USER button on BeagleBoard-xM
Modified bootcmd to check the staus at boot time and set
filename of the boot script.
* Moved to a BeagleBoard specific file.
* Removed changes to default boot command from adding userbutton
command.
* Made to handle pre-xM boards.
* Flipped polarity of the return value to avoid confusion. Success (0)
is when the button is pressed. Failure (1) is when the button is NOT
pressed.
* Used latest revision getting function.
* Used latest macros for board revision.
* Added xM-C revision definition (optional, since it was default)
* updated default configuration with UserButton functionality
* Added a separate bootenv variable to load a user defined .txt file
* Added an example, showing how a different environment file can be loaded with
the user button pressed

The below patch reverses the order of two segments in the board file.
Output pins need to have their values initialized, before they are
exposed to the logic outside the chip.

The reset sequence/configuration for ehci is highly board specific,
so this will be done in the source for the board, instead of
introducing several CONFIG_* which would be needed to make those
few lines in beagle.c usable across different OMAP boards.

Patch was updated by Jason Kridner <jkridner@beagleboard.org>:
* Use tabs to match style of other board revisions
* Only include board revisions that exist
* Default to the same configuration as the latest revision, but
without setting 'beaglerev'

It can be optimised out by the compiler otherwise resulting
in obscure errors like a board not booting.
This has been documented in README since 2006 when these were
first fixed up for GCC 4.x.

Beagle expansion boards contain an i2c eeprom to identify themselves.
This patch adds code to read and parse the eeprom contents. It prints
the expansion board name and revision and modifies environment variables
as appropriate. This patch is based on the Overo expansion board code.

This patch adds support for the Beagle xM. It uses the board ID
GPIO bits to recognize this revision and perform appropriate setup.

Not all boards have both LEDs hooked, so enabling both on
boards with single LED will just waste power. Make it
possible to choose LEDs by adding argument to
twl4030_led_init().
Using this turn on only LEDB for pandora, leave both LEDs
on for all other boards, as it was before this patch.

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.

There is no new functionality in the change.
This change is a conversion from the using raw register access to using
the OMAP3 GPIO API described in doc/README.omap3.

The Beagle Rev C boards pull UART2 from an alternate set of balls.

With BeagleBoard revision C some HW changes are introduced (e.g. PinMUX)
which might need different software handling. For this, GPIO pin 171 (GPIO
module 6, offset 11) can be used to check for board revision. If this pin
is low, we have a rev C board. Else it must be a revision Ax or Bx board.
To handle board differences you can call function beagle_get_revision().
E.g.:
if (beagle_get_revision()) {
/* do special revision C stuff here */
}
