@ -2393,14 +2393,6 @@ Low Level (hardware related) configuration options:
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]
