                If this macro is defined, then CONFIG_SYS_CCSRBAR_PHYS will be
                forced to a value that ensures that CCSR is not relocated.
 
-- CONFIG_IDE_AHB:
-               Most IDE controllers were designed to be connected with PCI
-               interface. Only few of them were designed for AHB interface.
-               When software is doing ATA command and data transfer to
-               IDE devices through IDE-AHB controller, some additional
-               registers accessing to these kind of IDE-AHB controller
-               is required.

 - CONFIG_SYS_IMMR:     Physical address of the Internal Memory.
                DO NOT CHANGE unless you know exactly what you're
                doing! (11-4) [MPC8xx systems only]
