Subject: Problem on recognise the CFI flash chip on SC520CDP

Hi David,

We got through the kernel compilation process but we encountered another
problem on recognising the CFI flash chip. I have compared with the boot
up process of other people. They usually have the CFI recongising but we
don't have, i.e. CFI: Found 4*8 device....

We use the on-board flash AMD29LV014B  x 4 Bank#0 & Bank#1

Could you please give us a hand to find out why?

Thanks and regards,

Jimmy
