-@chapter Memory Model
-A processor may support any combination of memory
-models ranging from pure physical addressing to complex demand
-paged virtual memory systems. RTEMS supports a flat memory
-model which ranges contiguously over the processor's allowable
-address space. RTEMS does not support segmentation or virtual
-memory of any kind. The appropriate memory model for RTEMS
-provided by the targeted processor and related characteristics
-of that model are described in this chapter.
-@section Flat Memory Model
-The i960CA supports a flat 32-bit address space with
-addresses ranging from 0x00000000 to 0xFFFFFFFF (4 gigabytes).
-Although the i960CA reserves portions of this address space,
-application code and data may be placed in any non-reserved
-areas. Each address is represented by a 32-bit value and is
-byte addressable. The address may be used to reference a single
-byte, half-word (2-bytes), word (4 bytes), double-word (8
-bytes), triple-word (12 bytes) or quad-word (16 bytes). The
-i960CA does not support virtual memory or segmentation.
-The i960CA allows the memory space to be partitioned
-into sixteen regions which may be configured individually as big
-or little endian. RTEMS assumes that the memory regions in
-which its code, data, and the RTEMS Workspace reside are
-configured as little endian.
