That's almost two years old.  Please upgrade.

Judging from this you seem to be using either P1010RDB or P1023RDS (or  
maybe some out-of-tree board?).  Always let us know what board you're  
talking about.

Because you don't have as much RAM on this board, or some other reason?

Did you update other relevant variables such as  
CONFIG_SYS_NAND_U_BOOT_DST and CONFIG_SYS_NAND_U_BOOT_START?

Plus you really should leave that 0x1000 offset in there.  On mpc85xx  
NAND boot, TEXT_BASE is 4K after the start of the image, since the boot  
page comes first.
