which are all the most possible reasons for these errors ?

First of all this is CUSTOM board similar to MPC8272ADS.
We are using flash which is different from flash that comes with the
MPC8272ADS board.
FLASH: S29GL256N90TF
Total size is 64 MB with 2 flash interleave
mapped at 0xfc000000.
>>Was it the physmap driver or the pq2fads driver that found the flash?
Flash is cfi compatible.

KERNEL: linux-2.6.10 and we r using arc/ppc
