Well in that case, you have on board programmable chip select's.
There must be registers that are associated with each chip select that define
the base physical address, the databus width, the wait states, what type of
is located there (read only or read/write) etc.
You must look for these registers and program them to an address that you
will be happy with.
Of course if the flash chips are already booting your bios etc. you
probably want to dump the contents
and decode what the base address is and just use that.
This is exactly like the AMD SC520 processor, except I doubt that the
registers to program the
chip selects are in the same location :)

Really your call. You can do both. The initrd will get you a pristine root
fs each time.
The root JFFS2 is more "direct" that you can make permanent changes to the
just by writing to the root fs.
