Notes:

1. DDR SDRAM and

on-chip SRAM can be located anywhere in the Local Memory area of the memory map.

2. The Boot ROM and Expansion ROM areas of the memory map are intended for use by ROM or Flash-type devices. While locating

volatile DDR SDRAM and SRAM in this region is supported, use of these regions for this purpose is not recommended.

3. When the optional boot from PCI-X memory is selected, the PCI-X Boot ROM address space begins at 2 FFFE 0000 (128 KB).
