spi flash through sport0 fails to be mounted.

the spi flash can be detected in booting up, but it would print error info when mounted and would make kernel panic if copy file to the mount directly.

Follow-ups

We need add pull-up to DRxPRI and DTxPRI of the sport-spi card respectively.

I've tried the spi flash card(with AT25df641),it works just fine.Only need to

set IC2 instead of IC3 on the spi-flash card.The M25P64 flash card fails on the

test,I believe it's the problem of the card itself.

Yes, reading and writing on AT25df641 are ok. So close this.
