+The memory map for U-Boot and linux has been extended w.r.t. the ADS
platform to allow for utilization of all 85xx CDS devices. The memory
map is setup for linux to operate properly. The linux source when
configured for MPC85xx CDS has been updated to reflect the new memory
The mapping is:

There is a switch which allows the boot-bank to be selected. The switch
settings for updating flash are given below.

the "flinfo" command. The secondary bank is always FF00_0000.
