2.6.10, Sharp chip, incorrect numparts (was: Intel chip)

Hi Dan,

Thank you for your reply.

First, please excuse me about the incorrect information - it
is Sharp chip and not Intel one.

My flash chip is lh28f640bfhe-pbtl90, 64M (4Mbit x 16), and
as Sharp docs say, its model no. is LHF64F12. It has 8
4Kword blocks at the beginning of the flash and then 127
32Kword blocks. There is just a single flash chip on the
board.

Yeah, months ago I noticed that the kernel understood only
the 64kiB blocks but not the 8KiB ones at the beginning of
the flash.

I have to admit I know almost nothing about the CFI and
flashes. But I can print out more flash info and do testing,
if needed.

Sorry again for misinformation,
Olav
