I have a pile of changes to u-boot that make yaffs work w/mtdparts (I.e. "ymount /<partition>" looks through mtdparts to find start/end blocks, etc) that works in u-boot-2011.06), and want to refresh that for a current u-boot, but it's gonna take time to get it into acceptable shape for submission.
If anyone wants the raw changes to get a head start I'm happy to pass them along...

Last time I looked, the yaffs code in u-boot is pretty old and I would recommend refreshing it.

While getting acquainted with possible u-Boot development

read FAQ "14.2.1. Can U-Boot be configured such that it can be started in RAM?" and was puzzled to learn that u-Boot cannot run from RAM.
you misread it. the question is for people who have loaded
u-boot, and
then want to load another copy of u-boot into ram and then execute
that
directly.
so the question is "can u-boot be *started in ram*" and the answer
is
"no".
The answer is "yes if you know how to do it" ;-)
The answer is "NO". You cannot load the _normal_ U-Boot image to RAM and start it. You must prepare a _special_ image which omits all the initializations that are normally included.
You can on PXA ;-)
This FAQ addresses the situation where people want to load and run their _normal_ images before burning these to flash. And this CANNOT be done like that.
You're certainly right this is true for general case, but there are special cases where you can load u-boot from u-boot without any harm (PXA is the
example).
