RE: Strataflash mapping problem


Hi Folks!
I was just poking around and it seems that my strata flash stuff never made
it into the repository.   Here it is again -- if any of you have issues with
it, please let me know, and I'll clean them up.

Hmmm... it looks like the last time I posted this I sent it to ecos-devel
instead of ecos-patches.  Sorry 'bout that chief!
