Are the small-sector Atmel flash (ie 29C010/29C040) parts supported by MTD?
These are the parts with 128/256 Byte sector size (ie 1024 128 byte sectors
in the '010, and 2048 256 byte sectors in the '040), with no explicit erase
command required before writing new data.

Other atmel parts are. If they aren't cfi then there is the issue
that they aren't in the table jedec_probe.c. But it should be trivial
to add them.

I think the other supported Atmel parts are the ones with the conventional
command set. These ones are different. It's not too hard to write support
for them though.

I am trying to modify the board specific routine "flash.c" to perform erase,
write and other procedure on my custom board (that use an mpc8260 and is
derived from est8260).
We are using an ATMEL AT49BV1614-90TI but unfortunately we are not able to
read the product IDs.
We have tested the same code with a Fujitsu MBM29LV160B (which should be
compatible) and it is working.
I have read the data sheet carefully but I did not see any evidence?
Anybody knows if there is some trick to apply?
