[ECOS] Flash infrastructure rework
Fri Aug 6 16:40:00 GMT 2004
Some time back I wrote a generic cfi flash driver for our proprietary
system. Since we were thinking of making a possible port to the eCOS from
proprietary operating system I made the api so that they could be easily
with ecos operating system. I was planning to clean up the API's and post it
We have tested the flash drivers on following flashes and they seems quite
- CSR/Fujitsu Flashes
Being new to eCOS Iam not really sure about the exact procedure for
patch, But I'll be glad to share my code if you are interested.
