Reset any i2c devices that may have been interrupted during a system reset.
Normally this would be accomplished by clocking the line until SCL and SDA
are released and then sending a start condtiion (From an Atmel datasheet).
There is no direct access to the i2c pins so instead create start commands
through the i2c interface.  Send a start command then delay for the SDA Hold
time, repeat this by disabling/enabling the bus a total of 9 times.

Rather than maintain/extend the current ifeq($(ARCH)) mess that exists in
the standalone Makefile, push the setting up of LOAD_ADDR out to the arch
config.mk (and rename to STANDALONE_LOAD_ADDR in the process).  This keeps
the common code clean and lets the arch do whatever crazy crap it wants in
its own area.

Cast first parameter to sata_cpy()

In /drivers/block/ata_piix.h, ata_id_has_lba48(), ata_id_has_lba(),
ata_id_has_dma(), ata_id_u32(), ata_id_u64() are all defined in
include/libata.h which is included in ata.h which is included by all files
which include ata_piix.h (only ata_piix.c) so these definitions are
supurflous to (and conlict with) this in libata.h. Interestingly, my
compiler complains about ata_id_u64 already being defined, but not
ata_id_u32

ata_dump_id() is defined in include/libata.h and should not be static
(maybe should even use ata_dump_id() in libata.c

Atmel DataFlashes by default operate with pages that are slightly bigger
than normal binary sizes (i.e. many are 1056 byte pages rather than 1024
bytes).  However, they also have a "power of 2" mode where the pages show
up with the normal binary size.  The latter mode is required in order to
boot with a Blackfin processor, so many people wish to convert their
DataFlashes on their development systems to this mode.  This standalone
application does just that.

If the memory layout pushes the stack out of the default DCPLB coverage,

Since the Blackfin ABI favors higher scratch registers by default, use the
last scratch register (P3) for global data rather than the first (P5).
This allows the compiler's register allocator to use higher number scratch
P registers, which in turn better matches the Blackfin instruction set,
which reduces the size of U-Boot by more than 1024 bytes...
