There is example bootloader code for booting from yaffs in boot.c, so I went
to see how big it was (I think it's less than 2K) but then
I noticed this isn't in my version of yaffs from CVS. Charles - is this code
not in CVS yet or am I being dumb?

I'm pretty sure you can easily get a first-stage loader into your 16K which
will read a file out of the YAFFS root. The example code is not a full YAFFS
reader but it is enough to read a file from the root so you can run it.

Whilst I'm here - sorry viewcvs has been broken for a while - I've put the
site onto a virtual server and it broke due to security paranoia. I'll fix
it soon.
