10.3.9.3. The Boot Region

The boot region is 1 MB in size, based at address 0. After power‑on, or after reset of the system interconnect, the boot region is occupied by the boot ROM, allowing the Cortex*-A9 MPCore to boot. Although the boot region size is 1 MB, accesses beyond 128 KB are illegal because the boot ROM is only 128 KB.

The 1 MB boot region can be subsequently remapped to the bottom 1 MB of SDRAM region by adjusting the L2 cache address filter.

Note: Alternatively, the boot region can be mapped to the 256 KB on‑chip RAM.
