Hello, I am currently trying to turn on MTD driver for above hardware 
configuration.

MTD core support
ROM chips in bus mapping
CFI support
physical mapping of flash chip.

but after boot my kernel, there is nothing happen to the MTD driver. It 
seems it does not working at all.

does any one can tell me what kinds of config I should use. to make it 
working??
