Flash with boot blocks in kernel 2.4

Flash with boot blocks in kernel 2.4

[JobHunts02]

I am working with kernel 2.4 on a board with two flash chips that have boot 
blocks, Intel Advanced Boot Block Flash Memory (28F320C3).  I just read that 
"the 2.4 CFI code handles only devices with uniform eraseblock size -- not the 
devices with 'boot blocks'. Current CVS fixes that for AMD chips, and it's 
trivial to do the same for Intel chips, now it's been done once," according to the 
MTD project leader. 

Does anyone know where on the web I can find these "trivial" changes for 
Intel chips? 

Thank you.

Newer MTD rev's fix this.  Back porting a new MTD should help you.

FYI - I don't think JFFS2 can span boot blocks and regular block,
though now that I think of it I've never tried.  Anybody know if
that's true or not?
