I'm sorry for double post ( by mistake I rejected ecos-devel from CC )

Hi John,

As far as I can recall the driver was not CDLized much (it was designed
only for lpc22xx parts in a mind (i.e. for its internal flash geometry:
8x8K + 2x64K + 8x8K and it manages only those last eight 8K sectors).
It seems to me it was implemented before a merge with flashv2 code. I
recall that I played with the driver in RedBoot on Olimex LPC-H2294
header board, but, I have to re-test it with nowadays CVS stuff. I will
try to do it this evening and let you know. However, I think that driver
can be used on olpch2294, olpcl2294, olpce2294 and phycore229x targets
when eCos legacy flash API is used.
