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.

This patch does the following
1) Enables the NAND driver which is now available.
2) Enables the 'CONFIG_MTD_DEVICE' as without this the
compilation will fail
3) We now have a safe place to store environment and defines
an offset where this can be stored. This offset value is such that it is after
the location where U-Boot is flashed using TI flash utilities.
4) Enables Bootdelay
5) Increases malloc() arena size. Manufacturers are coming out with
NAND with large blocks sizes of upto 1 MiB. It has been noticed that
as the block size of the NAND used is increased, if this particular
value is not increased, the NAND driver will output out of memory
errors.

v7_flush_dcache_all, because it depends on omap ROM code is not
generic. Rename the function to 'invalidate_dcache' and move it
to the omap cpu directory.
Collect the other omap cache routines l2_cache_enable and
l2_cache_disable with invalide_dcache into cache.S. This
means removing the old cache.c file that contained l2_cache_enable
and l2_cache_disable.
The conversion from cache.c to cache.S was done most through
disassembling the uboot binary. The only significant change was
to change the comparision for the return of get_cpu_rev from
cmp r0, #0
beq earlier_than_label
Which was lost information to
cmp r0, #CPU_3XX_ES20
blt earlier_than_label
The paths through the enable routine were verified by
adding an infinite loop and seeing the hang. Then
removing the infinite loop and seeing it continue.
The disable routine is similar enough that it was not
tested with this method.
Run tested by cold booting from nand on beagle and zoom1.

This feature is useful when your board uses different mii buses for different
phys and all (or a part) of these buses are implemented via bit-banging mode.
The driver requires that the following macros should be defined into the board
configuration file:
CONFIG_BITBANGMII - Enable the miiphybb driver
CONFIG_BITBANGMII_MULTI - Enable the multi bus support
If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs
to define at least the following macros:
MII_INIT - Generic code to enable the MII bus (optional)
MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional)
MDIO_ACTIVE - Activate the MDIO pin as out pin
MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin
MDIO_READ - Read the MDIO pin
MDIO(v) - Write v on the MDIO pin
MDC_DECLARE - Declaration needed to access to the MDC pin (optional)
MDC(v) - Write v on the MDC pin
The previous macros make the driver compatible with the previous version
(that didn't support the multi-bus).
When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill
the bb_miiphy_buses[] array with a record for each required bus and declare
the bb_miiphy_buses_num variable with the number of mii buses.
The record (struct bb_miiphy_bus) has the following fields/callbacks (see
miiphy.h for details):
char name[] - The symbolic name that must be equal to the MII bus
registered name
int (*init)() - Initialization function called at startup time (just
before the Ethernet initialization)
int (*mdio_active)() - Activate the MDIO pin as output
int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin
int (*set_mdio)() - Write the MDIO pin
int (*get_mdio)() - Read the MDIO pin
int (*set_mdc)() - Write the MDC pin
int (*delay)() - Delay function
void *priv - Private data used by board specific code
The board code will look like:
struct bb_miiphy_bus bb_miiphy_buses[] = {
{ .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... },
{ .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... },
...
int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) /
sizeof(bb_miiphy_buses[0]);

When U-Boot is relocated from flash to RAM pointers are modified
accordingly. However, pointers initialzed with NULL values should not
be modified so that they maintain their intended NULL value. If the
BSS segment is linked at address 0 its address will not be
updated as necessary during relocation.
This is a temporary workaround. The end goal is to add support to
U-Boot to dynamically locate the BSS at an arbitrary address at
runtime. When the ability to fixup the BSS inteligently is
added, this workaround can be removed and the 85xx link script
can put the BSS at a fixed address at link time.
