nor and nand on same system

nor and nand on same system

[Jim Stewart]

Dear list:

I am designing a system that may contain both nor and nand flash in the
same system (NAND flash for future expansion and nor for boot and root
fs).
I have looked over the MTD documentation, how-to's, etc. and it seems
that the driver level is linked to a SINGLE specific hardware
implementation. Is it possible to have two separate drivers -- one for
the nor device (probably using the current CFI drivers) and one for a
NAND device?

I plan on using the JFFS as the MTD client

Thanks,

Yep, each device has it's own driver. They live side by side, as long they 
arent configured to access the same physical device, which is unlikely for 
NAND and NOR.

JFFS does not support NAND, JFFS2 does
