After a reset, the boot ROM is at address 0. The first 64 MByte of EMC-SDRAM or EMC asyn memory (chip select
Bank0) can also be mapped to address 0 with the MEM_SWAP register in the SCRB (see 2.3.10.9.22).

ARM926 I-TCM can only be accessed internally from the ARM926 and not over the AHB. After activation, this ad-
dress range is no longer shown at the AHB. This range can also be shown at other addresses with alignment in seg-
ment 0, however not in the ARM926 D-TCM or ARM966 D-TCM area.
