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

Using the new env import command it is possible to use plain text files instead
of script-images. Plain text files are much easier to handle.
E.g. If your boot.scr contains the following:
-----------------------------------
setenv dvimode 1024x768-16@60
run loaduimage
run mmcboot
-----------------------------------
you could create a file named uEnv.txt and use that instead of boot.scr:
-----------------------------------
dvimode=1024x768-16@60
uenvcmd=run loaduimage; run mmcboot
-----------------------------------
The variable uenvcmd (if existent) will be executed (using run) after uEnv.txt
was loaded. If uenvcmd doesn't exist the default boot sequence will be started,
therefore you could just use
-----------------------------------
dvimode=1024x768-16@60
-----------------------------------
as uEnv.txt because loaduimage and mmcboot is part of the default boot sequence

CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool. In the result, all definitions of this value can be
deleted from the board config files. We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.
No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

This changes fixes an early i2c error.
It appears that I2C is working because once a read or write
error is detected, the omap24xx_i2c driver calls i2c_init
inside its error handling check.
While it is ok to attempt error handling this way, the boards
must not depend on this side effect to initialize it's i2c.
Instead of explicitly calling i2c_init for every board, use
the generic arm initialization in lib_arm/board.c. By defining
the config variable CONFIG_HARD_I2C, the omap3 i2c initialization
is included in the init_sequence table.
Run tested on Beagle.
Compile tested on the omap3's
