IIRC, then you have a custom PPC440 SoC. I have no idea which external bus 
controller (EBC) is used on your SoC. Is it the one also used on the 
AppliedMicro (AMCC) PPC4xx? Then you need to change the CONFIG_SYS_EBC_PBxCR / 
CONFIG_SYS_EBC_PBxAP defines. Take a look at the users manual for details. If 
you have a different EBC then I can't really help you here. Your SoC 
documentation should have all details you need.

Looking into the PPC440 users manual makes it clear. 64MByte as TLB size is 
not available. You need to define 4 16MB entries for this.
