[U-Boot] Trouble reading from PLD memory

I am trying to upgrade from u-boot-1.3.4 to u-boot-2010.9. My processor is an MPC8248. When my custom board boots up, I read an incorrect value from read-only programmable logic device (PLD) memory. Using the BDI2000, I have verified that the value in the PLD is what it was programmed to be. Using u-boot's md command, I get the same incorrect value that I got from my code by dereferencing a pointer to the address. With u-boot-1.3.4, the md command reads the PLD memory correctly, as does my code.
