Not quite. The patch to use interrupt masking instead of interrupt
disabling is not included. Also the patch to set some register fields is
not included. I have ported these patches to your latest patchset. There
will be 3 in all. I will post them shortly.

I tested your patchset "as is" and it works for the i.MX35 with a 16-bit
flash chip. I also tested ECC error detection and it is ok.

With an RT-kernel the driver has some interrupt issues, which are
resolved by the patch to mask instead of disabling interrupts (which I
will be posting shortly).
