LEVEL - specifies the ordering of the memory region. Lower regions
are searched first. Within a level, memory regions can not
overlap.
DEVICE, when non NULL, specifies a callback memory space.

MAPMASK - Bitmask specifying the memory maps that the region is to
be attached to. Typically the enums sim-basics.h:access_* are used.
MODULO, when the simulator has been configured WITH_MODULO support
ADDRESS_SPACE - For device regions, a MAP:ADDRESS pair is
translated into ADDRESS_SPACE:OFFSET before being passed to the
client device.
MODULO - when the simulator has been configured WITH_MODULO support
and is greater than zero, specifies that accesses to the region
[ADDR .. ADDR+NR_BYTES) should be mapped onto the sub region [ADDR
.. ADDR+MODULO). The modulo value must be a power of two.
OPTIONAL_BUFFER, when non NULL, specifies the buffer to use for
DEVICE - When non NULL, indicates that this is a callback memory
space and specified device's memory callback handler should be
called.
OPTIONAL_BUFFER - when non NULL, specifies the buffer to use for
data read & written to the region. Normally a more efficient
internal structure is used. It is assumed that buffer is allocated
such that the byte alignmed of OPTIONAL_BUFFER matches ADDR vis
(OPTIONAL_BUFFER % 8) == (ADDR % 8)). It is defined to be a sub-optimal
hook that allows clients to do nasty things that the interface doesn't
