more details. This shadow copy provides MMIO-space
access to this register. The P,T and M bitfields of this
MMIO register are read-only.
11.6.3
The DRAM_BASE and MMIO_BASE registers are not
normally written through MMIO; their value is determined
by the boot process. Though not recommended, the reg-
isters are writable in MMIO. Special care should be exer-
cised when writing these registers:

to space such writes far apart, or iterate until the first
register written to reads back with the new value
before writing the second one.
