More on the boot loader debate from Nick via me (he's not getting
balloon list email at the moment):
- we know bootldr is horrid in various ways and is missing a TCP/IP
stack and USB support (both of which would be nice to have) *but* there
is significant investment in automated mass-programming widgetry at Toby
Churchill which relies on it, so changing to a different boot loader
would require a lot of work for them.
- bootldr already has NAND and YAFFS support. Sorting these out in
another boot loader would be a non-trivial task, probably.
- Nick has bootldr basically ready to go for the PXA270, modulo a bunch
of #defines, so the process of getting it to run might be a morning's
work instead of <more than that>. Given the number of other things
clamouring for his attention, this is a Good Thing if he's got to do it.
