Description
Most real HW platforms alias different memory area to the same hardware location. Could it be possible to implement this feature into the Mapping Table ?
Example: Aliasing memory area on Mips platform in order to support 0x80000180 and 0xBFC00000 sharing the same memory as other memory area.

Interested people are warmly encouraged to commit such a component.

This feature is not related to the mapping table, which already can create routing tables making addresses 0x80000180 and 0xBFC00000 target the same component. On the other hand, the target component (a ram usually), may implement this feature.
Implementing such a new component basing your code on the VciRam should be easy. The most tricky part is to decide how to implement the configuration of your aliased segments.
