[U-Boot] [PATCH v2 0/5] Improve falcon mode and am335x_evm docs

[Tom Rini]

Hey all, 
 
The following 5 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 rest update slightly, and then document,
falcon mode for am335x_evm by providing examples for eMMC or raw SD cards,
FAT SD cards and NAND and provide some general information setting up
falcon mode. In the updates side, the DFU info to be able to write the
falcon mode areas is added 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. 

Changes in v2:
- Add Peter's Reviewed-by to #1
- Split the previous #2 into 4 patches
