Well,  Here's a new guy to the crowd.

I've Just started playing with the MTD drivers for linux and I have a couple
of questions.
I am currently working on a project that (will) store the linux kernel/os on
flash.  We are useing the ElanSC400 chip and a board that has 3 pairs of
AM29F016EC Flash Chips arranged such that the high byte of the data goes to
one chip and the low byte goes to the other.  I was wondering if the MTD
supports this?  These chips are JEDEC compatiable.

Also I wrote a test program that run in user space and I tried using mmap()
to read the device and it seems to work OK as long as I map /dev/mem as
MAP_PRIVATE.  I would like to be able to write to Memory < 1M directly.  If
I change the flage to MAP_SHARED, mmap() falied with "Permision denied"  Any
