JFFS2 peoblems with K3 strata flash on Dalhart

[Gu Susan-w15879]

Does K3 (and Dalhart) be configured as "burst" read mode when system is reset?

Er, I don't think there have been significant changes since then. Updating 
to the latest code certainly can't hurt though.

The problem is that the chip write() call is returning zero (i.e. no error) 
but is setting the number of written bytes to zero. That doesn't make sense 
-- if it didn't write all the bytes we asked it to, then there must have 
been an error.

This chip supports buffer writes, doesn't it? Can you add some extra 
'printk' calls in cfi_intelext_write_buffers() to try to show what's 
happening to 'retlen' and when it returns.
