Add support to use second and third I2C bus, too.
Bus 0 is still the default, but by calling i2c_set_bus_num(1/2) before doing
I2C accesses, code can switch to bus 1 and 2, too. Don't forget to switch
back afterwards, then.

The asm-arm/unaligned.h includes linux/unaligned/access_ok.h
This file is unsafe to be used on ARM, since it does an unaligned memory
accesses which fails on ARM.
Lookin at Linux the basic difference seems to be the header
"include/asm-arm/unaligned.h". The Linux version of "unaligned.h"
does *not* include "access_ok.h" at all. It includes "le_byteshift.h"
and "be_byteshift.h" instead.

Due to new TI boards being added to U-Boot, the hardware.h
is getting very messy. The warning being fixed is due to
the EMIF addresses being redefined.
The long term solution(after 2009.11) to this is to
have SOC specific header files.

Some DaVinci SOC's use GPIOs to enable EMAC and DM9000.
This patch adds some definitions for GPIO registers and also adds
structures for GPIO.
A separate header file is being added so that in future we
can have a DaVinci GPIO driver similer to OMAP.

In the DaVinci specific code, we use both CONFIG_SOC_DM646X and
CONFIG_SOC_DM646x to represent DM646x specific code.
This patch changes occurrences of CONFIG_SOC_DM646x to
CONFIG_SOC_DM646X. This is because for DM644x series of SOCs we use
the flag CONFIG_SOC_DM644X. We want some uniformity.

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.
Compile tested on MAKEALL arm.

These architectures don't need relocation fixups, so reduce their
codesize a bit by defining CONFIG_RELOC_FIXUP_WORKS.
Also remove the reloc_off field from their global data structures
as it is no longer needed.
Note that the location of the standalone application jump table pointer
in the global data structure is affected by this change, breaking
execution of standalone applications compiled for previous versions of
U-Boot. We will therefore increment XF_VERSION in the next commit,
which also touches this area.

This feature can be used to trigger special command "sysrstcmd" using
reset key long press event and environment variable "sysrstdelay" is set
(useful for reset to factory or manufacturing mode execution)
Kirkwood SoC implements a hardware-based SYSRSTn duration counter.
When SYSRSTn is asserted low, a SYSRSTn duration counter is running.
The counter value is stored in the SYSRSTn Length Counter Register
The counter is based on the 25-MHz reference clock (40ns)
It is a 29-bit counter, yielding a maximum counting duration of
2^29/25 MHz (21.4 seconds). When the counter reach its maximum value,
it remains at this value until counter reset is triggered by setting
bit 31 of KW_REG_SYSRST_CNT
Implementation:
Upon long reset assertion (> ${sysrstdelay} in secs) sysrstcmd will be
executed if pre-defined in environment variables.
This feature will be disabled if "sysrstdelay" variable is unset.
for-ex.
setenv sysrst_cmd "echo starting factory reset;
nand erase 0xa0000 0x20000;
echo finish ed sysrst command;"
will erase particular nand sector if triggered by this event

The addresses are for the twl4030.
The prescalar that converts the function clock to the sampling
clock is hardcoded to 0. The reference manual recommends 7
if the function clock is 96MHz.
Instead of just changing the hardcoded values, the prescalar
is calculated from the value I2C_IP_CLK.
The i2c #defines are in kHz. The speed passed into the
i2c init routine is in Hz. To be consistent, change the
defines to be in Hz.
The timing calculations are based on what is done in the
linux 2.6.30 kernel in drivers/i2c/buses/i2c_omap.c as
apposed to what is done in TRM.
The major variables in the timing caculations are
specified as #defines that can be overriden as required.
The variables and their defaults are
I2C_IP_CLK SYSTEM_CLOCK_96
I2C_INTERNAL_SAMPLING_CLK 19200000
I2C_FASTSPEED_SCLL_TRIM 6
I2C_FASTSPEED_SCLH_TRIM 6

I2C_HIGHSPEED_PHASE_ONE_SCLH_TRIM I2C_FASTSPEED_SCLH_TRIM
I2C_HIGHSPEED_PHASE_TWO_SCLL_TRIM I2C_FASTSPEED_SCLL_TRIM
I2C_HIGHSPEED_PHASE_TWO_SCLH I2C_FASTSPEED_SCLH_TRIM
This was runtime verified on Zoom1, Zoom2, Beagle and Overo.
The 400kHz and 3.4M cases were verifed on test Zoom1,
Zoom2, Beagle and Overo configurations.
Testing for omap2 will be done in a second step as Nishanth
