You can't runtime configure it (it's a bunch of signals into the
core that determine where the decoder sits the peripherals in
the memory map). However, the CBAR register which on reset
starts out with the value of the base address is a writable
register (writing it won't change where the peripherals live,
it just reads-as-written).
