As you know, the memory in the picture below is divided into two parts: PA(2G) and DSP(2G) . But now, we want to configure the PA into 4G, DSP into 2G. We have two kinds of
schemes, but we don't know whether it is feasible
and how to implement it:

  1. The Physical address of PA is Configured from 0x00000000 to 0xFFFFFFFF,
    Then assign DSP the other 2G memory.
  2. The Physical address of PA and DSP  remains the same, and assign PA the
    other 2G memory.

How do you think ofthis two methods? If one of the methods is feasible, could you
tell me how to implement it?
