disable caches before booting an app for Blackfin apps
It isn't generally save to execute applications outside of U-Boot with caches
enabled due to the way the Blackfin processor handles caches (requires
software assistance). This patch disables caches before booting an ELF or
just booting raw code. The previous discussion on the patch was that we
wanted to use weaks instead, but that proved to not be feasible when multiple
symbols are involved, which puts us back at the ifdef solution. I've
minimized the ugliness by moving the setup step outside of the main function.

LM73 bug fix for negative temperatures and cleanup
When the LM73 temperature sensor measures a temperature below 0 C, the
current driver does not perform sign extension, so the result returned is
512 C too high. This patch fixes the problem, and does general cleanup
of the code.
cfi_flash: Support buffered writes on non-standard Spansion NOR flash
Some NOR flash chip from Spansion, for example, the s29ws-n MirrorBit
series require different addresses for buffered write commands. Define a
configuration option to support buffered writes on those chips. A more
elegant solution would be to automatically detect those chips by parsing
their CFI records, but that would require introduction of a fixup table
into the cfi_flash driver.

Fix fdt set command to conform to dts spec
The fdt set command was treating properties specified as <00> and <0011>
as byte streams, rather than as an array of cells. As we already have
syntax for expressing the desire for a stream of bytes ([ xx xx ...]),
we should use the <> syntax to describe arrays of cells, which are always
32-bits per element. If we imagine this likely (IMHO) scenario:
> fdt set /ethernet-phy@1 reg <1>
With the old code, this would create a bad fdt, since the reg cell would be
made to be one byte in length. But the cell must be 4 bytes, so this would
break mysteriously.
Also, the dts spec calls for constants inside the angle brackets (<>)
to conform to C constant standards as they pertain to base.
Take this scenario:
> fdt set /ethernet@f00 reg <0xe250000\ 0x1000>
The old fdt command would complain that it couldn't parse that. Or, if you
wanted to specify that a certain clock ran at 33 MHz, you'd be required to
do this:
Lastly, the fdt print code was rearranged slightly to print arrays of cells
if the length of the property is a multiple of 4 bytes, and to not print
leading zeros.
