reboot problem with jffs2

[Jianlin Zeng]

Hi Dave,

Thanks for your information! It appears that I need to
set all flash sectors to read mode before reboot,
otherwise the CPU won't be able to read any boot code
from the flash after reboot. Don't know the reason
behind it but once I did that the reboot works fine.

Regards,
Jianlin
