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

OMAP3 Beagle Pin Mux initialization glitch fix
The below patch reverses the order of two segments in the board file.
Output pins need to have their values initialized, before they are
exposed to the logic outside the chip.

da850: modifications for Logic PD Rev.3 AM18xx EVM
AHCLKR/UART1_RTS/GP0[11] pin needs to be configured for
NOR to work on Rev.3 EVM. When GP0[11] is low,
the SD0 interface will not work, but NOR flash will.
da850: fix the channel number for EMAC teardown init
TX and RX channel numbers programmed as '1' during EMAC
teardown initialization is wrong. This patch fixes the
same by setting channel number to '0' which is used by U-boot.
da850: add support for Spectrum Digital AM18xx EVM
The AM18xx EVM contains winbond SPI flash instead of ST SPI flash in
comparison with logic PD da850/omap-l138 EVM. So enable configuration
to look for winbond flash.
da850: add support to wake up DSP during board init
add support for DSP wake-up by default on DA850/OMAP-L138
during board initialization. Enable hwconfig environment and added
extra env setting through CONFIG_EXTRA_ENV_SETTINGS.
To prevent DSP from being woken up,set the environment variable as,
set hwconfig "dsp:wake=no"
da850: indicate cache usage disable in config file
there are cache coherency issues when using the DAVINCI Ethernet driver,
hence caches cant be used for da850 u-boot. As per new cache management
framework,if the caches are not used in u-boot, it needs to be explicitly
indicated through macros in config file. CACHE disable is indicated by
the following macro definitions in config file,

omap3:clock: check cpu_family before enabling clks for IVA & CAM
In case of AM3517 and AM3505 (which is OMAP3 varients), IVA2 and
ISP-CAMERA modules have been removed. So add check for cpu_family before
enabling clocks for these modules, else this impacts subsequent
power consumption and system suspend/resume functionality.
omap3:clock: configure GFX clock to 200MHz for AM/DM37x
AM/DM37x is another OMAP3 variant, where the GFX clock has been
boosted to 192MHz/200MHz. So fix the GFX_DIV value for this change.
HW Errata: Due to dependency of TV out clock of 54MHz, it is not
possible to configure GFX to 192MHz. So as per HW errats, the
recommended GFX clock is 200MHz (=CORE_CLK/2).
Increase the console I/O buffer size (SYS_CBSIZE) to 512 (from 256)
required especially for bootargs string, as multiple options
(e.g Video settings) are passed to the kernel through bootargs.

arm: do not force d-cache enable on all boards
c2dd0d45540397704de9b13287417d21049d34c6 added dcache_enable()
to board_init_r(). This enables d-cache for all ARM boards.
As a result some of the arm boards that are not cache-ready
are broken. Revert this change and allow platform code to
take the decision on d-cache enabling.
Also add some documentation for cache usage in ARM.
This patch adds support for software I2C for GONI and Universal C210 reference targets.
It adds support for access to GPIOs by number, not as it is present,
by bank and offset.

ARM: MX51: PLL errata workaround
This is a port of the official PLL errata workaround from Freescale to
mainline u-boot.
The PLL's in the i.MX51 processor can go out of lock due to a metastable
condition in an analog flip-flop when used at high frequencies.
This workaround implements an undocumented feature in the PLL (dither
mode), which causes the effect of this failure to be much lower (in terms
of frequency deviation), avoiding system failure, or at least decreasing
the likelihood of system failure.

mmc: S5P: Support DMA restarts at buffer boundaries
Currently if a DMA buffer straddles a buffer alignment boundary
(512KiB) then the DMA engine will pause and generate a DMA
interrupt. Since the DMA interrupt is not enabled it will hang
the MMC driver.
This patch adds support for restarting the DMA transfer. The
SYSTEM_ADDRESS register contains the next address that would have
been read/written when a boundary is hit. So we can read that
and write it back. The write triggers the resumption of the
transfer.
