razia razia (INDIA)
I am working on a CFI compliant Parallel NOR Flash connected to our ADSP-BF527 0.2 custom board.
I am using uClinux-dist-2009R1-RC1 distribution.
The Flash size is 16MB, Physically it is connected to the AMS0# and Latch bits are used for additional addressing of the flash chip.
For this, a flash mapping driver is created which is very similar to the "gpio-addr-flash" mapping driver, already available in the MTD subsystem in the kernel. (source file ---linux-2.6.x/drivers/mtd/maps/gpio-addr-flash.c).
This type of mapping driver will be useful in the cases,where gpio -pins(PF Pins) are not available for additional addressing of the flash chip.
Shall I submit the code for your reference,so that you can add it to the kernel if you find the code is worth for usage.

any body can post drivers for inclusion. the barrier for acceptance is quality of code, not the person submitting.
