Overo 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.

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.

The purpose of this patch is to prepare for adding the OMAP4 architecture, which is Cortex A9
Cortex A8 and A9 both belong to the armv7 architecture, hence the name change.
The two architectures are similar enough that substantial code can be shared.

Add setup for ethernet on Tobi, allowing kernel/ramdisk to be loaded
over tftp.
This also refactors the smc911x driver to allow for detecting when the
chip is missing. I.e. the detect_chip() function is called earlier and
will abort gracefully when the Chip ID read returns all 1's.

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

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.

Use the functions print_cpuinfo() and checkboard() to

These functions reuse content from the existing function
display_board_info() - which has been removed.
Also, updated the existig OMAP3 configurations to

- CONFIG_DISPLAY_CPUINFO

According to the doc/feature-removal-schedule.txt, the "autoscr"
command will be replaced by the "source" command in approximately 6
months from now.
This patch prepares this change and starts a 6 month transition
period as follows:
- The new "source" command has been added, which implements exactly
the same functionlaity as the old "autoscr" command before
- The old "autoscr" command name is kept as an alias for compatibility
- Command sequences, script files atc. have been adapted to use the
new "source" command
- Related environment variables ("autoscript", "autoscript_uname")
have *not* been adapted yet; these will be renamed resp. removed in
a separate patch when the support for the "autoscr" command get's
finally dropped.
