Did you get some strange behaviors after a "warm reboot" from linux ? A week that i'm using a new u-boot but i catch some strange behavior after a reboot from linux.
there may some issue since linux can set the flash into another (4byte) addressing mode which can cause trouble if u-boot try read with the standard adressing mode (3byte).
i've seen on some hardware platforms that there is a reset signal wired to the flash which resets this addressing mode setting on warm restart.
