To support driver model and device tree, use the SPI-flash-based
AT45xxx DataFlash driver, DataFlash is a kind of SPI flash.
Instead of ATMEL_DATAFLASH_SPI DataFlash older driver that will
be removed in the future.

Add the dts files to support deivce tree, update the configuration
files to support the device tree and driver model. The peripheral
clock and pins configuration are handled by the clock and the pinctrl
drivers respectively.
Enable the early debug UART to debug problems when an ICE or other
debug mechanism is not available.

Strings read from devices may sometimes fail to be
NULL-terminated. The functions in lib/string.c are subject to
failure in this case. Protect against observed failures in
set_gpt_info() by switching to length-checking variants with a length
limit of the maximum possible partition table length. At the same
time, add a few checks for NULL string pointers.
Here is an example as observed in sandbox under GDB:
=> gpt verify host 0 $partitions
Program received signal SIGSEGV, Segmentation fault.

This patch provides support in u-boot for renaming GPT
partitions. The renaming is accomplished via new 'gpt swap'
and 'gpt rename' commands.
The 'swap' mode returns an error if no matching partition names
are found, or if the number of partitions with one name does not equal
the number with the second name. The 'rename' variant always
succeeds as long as a partition with the provided number exists.
Rewriting the partition table has the side-effect that all partitions
end up with "msftdata" flag set. The reason is that partition type
PARTITION_BASIC_DATA_GUID is hard-coded in the gpt_fill_pte()
function. This does not appear to cause any harm.

In order to read the GPT, modify the partition name strings, and then
write out a new GPT, the disk GUID is needed. While there is an

The existing partitions-list parsing in cmd/gpt.c passes a value
from gpt_default() to set_gpt_info() that README.gpt suggests
should begin with 'partitions='. Partition-list strings should
in fact begin with 'uuid_disk', as otherwise the call from
set_gpt_info() to extract_val() to find 'uuid_disk' will fail.
Change README.gpt accordingly.

Not using board revision is causing confusion about which board is
supported and tested. Mark dts files exactly with board revision which

tools are parsing this string and can change behavior depends of board
revision.
