3.10.3. Remapping and DRAM aliasing

The EB hardware provides considerable memory remap functionality. During this boot remapping, the bottom 64MB of the physical address map can be:

In addition to providing remap functionality, the hardware aliases all 256MB of system DRAM at 0x70000000.

Remapping does not typically apply to the system models. However, NOR flash is modeled and can be remapped. See Switch S8.

In the memory map, memory regions that are not explicitly occupied by a peripheral or by memory are unmapped. This includes regions otherwise occupied by a peripheral that is not implemented, and those areas that are documented as reserved. Accessing these regions from the host processor results in the model presenting a warning.
