Memory Protection (Attributes)

[Gedare Bloom]

Hi,
I am working to bring primitives for real-time memory protection to
RTEMS, and as a first step I have designed a solution for
setting/enforcing attributes on memory regions. The design is in three
layers: a high-level API (cpukit) layer, a middle layer for CPU family
support (libcpu), and a low-level layer for hardware-specific support
(libcpu/libbsp).

I have written a description of the API layer [1] and would appreciate
any feedback. I prefer to have the feedback given publicly to the
rtems-devel mailing list thread [2] (or privately to me directly).

I will describe the other layers in the near future.
