The System Controller’s peripherals are all mapped within the highest 16K bytes of address
space, between addresses 0xFFFF C000 and 0xFFFF FFFF.
However, all the registers of System Controller are mapped on the top of the address space.
This allows addressing all the registers of the System Controller from a single pointer by using
the standard ARM instruction set since the Load/Store instructions have an indexing mode of +/-
4kbytes.
