[U-Boot] [PATCH 0/2] Update Falcon Mode docs

[Tom Rini]

Hey all,

The following 2 patches update docs for falcon mode, and am335x_evm.  The
first adds a quick general note about how failure is decided in falcon mode
and we drop back to U-Boot.  The second adds a README for am335x_evm which
provides examples for eMMC or raw SD cards, FAT SD cards and NAND for
setting up falcon mode.  This also updates the DFU info to be able to write
these areas and corrects a small bug in the NAND configuration for falcon
mode.  I did this in part because while I found doc/README.falcon helpful
we still want to provide board-specific examples when possible I believe.

And, as has been pointed out to me on IRC, this isn't a huge boot time win
(and may be a loss) until we have dcache configured correctly.  This is on
my TODO list, but a separate patch.
