David,

I have a feeling that the Flash interface on the 88W8388 will not meet our 
performance requirements since its purpose is to access firmware.

A solution using the 88W8388's flash controller  will have a relative long 
path from the main CPU to the flash (GX2 <-> 5536 <-USB-> 88W8388 <-> 
Flash).
Such a chain will make it hard to run JFFS2 on, am I missing something?

Mark Foster has already started looking for an ASIC solution for 
interfacing the flash (separately from the DCON chip) via PCI.

Should we really pursue the 88W8388 option with Marvell?

M.

I think that should be possible. The last few messages were copied to
the libertas-dev mailing list in the hope that the Marvell engineers
subscribed there would respond, but they don't seem to have done so
yet...
