The old swap function tended to clobber unrelated pins and screw up masks.
Rewrite the thing from scratch so it only uses the resources it needs.

The BF53x/BF56x parts do not have an on-chip ROM to boot LDRs out of
arbitrary memory locations, so implement a basic one in software.

Now that real documentation has been released for the OTP interface and
the on-chip ROM wrt writing/timings, implement support for reading/writing
as well as dumping/locking.

This brings the API for the on-chip ROM in line with the toolchain and
hardware documentation.

Some devices have no UART device pulled out, so allow people to disable the
driver completely in favor of other methods (like JTAG-console).

The Blackfin JTAG has the ability to pass data via a back-channel without
halting the processor.  Utilize that channel to emulate a console.

Make sure we save the value of RETX at power on and then pass it on to the
kernel so that it can nicely debug a "double-fault-caused-a-reset" crash.

People often ask questions about the init process and when things go
from flash to relocated base, so clarify the comments a bit.

No need to set the SP register indirectly to the configured value when it
can be set directly.

As pointed out by Ivan Koryakovskiy, the initialization code was not
actually respecting the CONFIG_CLKIN_HALF option when configuring the
PLL_CTL register.

Rather than using a local custom memcpy function, just call the existing
optimized Blackfin version.

The BF538/BF539 use CS2 for booting off of rather than CS1 like newer
Blackfin parts.

This video driver used to live in the Blackfin cpu directory, but it was
lost during the unification process.  This brings it back.

No functional changes here; just cleanup code style a bit.

The DEBUG code in initdram() is quite old and was never really useful, so
just drop it altogether.  Common Blackfin debug code does a better job.

Some of the flash defines weren't in the correct location and caused build
problems in some configurations, so let's move types and defines to better
local locations.

The current Blackfin i2c driver does not work properly with certain devices
due to it breaking up transfers incorrectly.  This is a rewrite of the
driver and relocates it to the newer place in the source tree.

Also remove duplicated I2C speed defines in Blackfin board configs and
disable I2C slave address usage since it isn't implemented.

Respect the CONFIG_SYS_MONITOR_LEN define rather than assuming a size of
128kB when setting up the default flash protection region for U-Boot
itself.

When setting up the global data, rather than relying on sizeof(), use the
common CONFIG_SYS_GBL_DATA_SIZE define.

Here are the Blackfin-specific and board-independent pieces for status leds.

The common code takes care of calling i2c_init() when needed, so no point
in us doing it as well.

Our dcache invalidate function doesn't just invalidate, it also flushes.
So rename the function accordingly and fix the dma_memcpy() function so it
doesn't inadvertently corrupt the data destination.

Creating a new dma_memcpy() function that skips all cache checks allows us
to use the function in very early init where the cache is not yet setup.
