The following RedBoot configurations are supported:
A device programmer is used to program socketed flash parts.
The first level page table is located at physical address 0xc0004000. No second level tables are used.
NOTE: The virtual memory maps in this section use a C and B column to indicate whether or not the region is cached (C) or buffered (B).

The SA11x0 OS timer is used as a polled timer to provide timeout support for XModem file transfers.
These shell variables provide the platform-specific information needed for building RedBoot according to the procedure described in Chapter 3:
