Add parameters to the OMAP MMC initialization function so the board can
mask host capabilities and set the maximum clock frequency. While the
OMAP supports a certain set of MMC host capabilities, individual boards
may be more restricted and the OMAP may need to be configured to match
the board. The PRG_SDMMC1_SPEEDCTRL bit in the OMAP3 is an example.

gpio_free() should not have the side effect of setting the line to input since this prevents the gpio command from being able to set a line as output.

By moving the CS4 configuration into the board specific configuration, it
is left free for custom carrier boards. The USRP-E1XX series uses
CS4 to control access to an FPGA, so without this patch the device driver
cannot claim CS4.

The existing timing does not quite meet the minimum requirements
in the LAN9221 datasheet. The timing in this patch solves problems
noticed on some parts. The patch also combines the CS configuration
for the overo and igep0020 boards per request.

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.

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.

An upcoming version of Overo uses a Wifi/BT module with 1.8V signaling,
eliminating the need for an external transceiver to handle the level
shifting. This patch detects whether an external transceiver is present
and adjusts the pinmux settings as appropriate.

The latest Overo COM modules encode their revision number on
GPIOs 115, 113, and 112. All boards to date have no pullups on these pins
and hence appear as revision 0.
This patch reads and prints the revision information.

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.

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.

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.
