Benjamin Walsh 0e6aebf2c9 tests/mem_safe: place test buffers at the edges of RAM
This test checks if it can write at the edges of RAM within the kernel
image. The problem is that this memory is not meant to be trampled on.

With the help of custom linker scripts, place 32-byte buffers at those
edges.

Only linker scripts for QEMU on x86 and Cortex-M3 are provided, to avoid
having to maintain too many of them, in case the reference linker
scripts in the kernel change.

Title: Safe Memory Access

Description:

This test verifies that the safe memory access (_mem_safe) functions as
intended.

---------------------------------------------------------------------------

Building and Running Project:

This nanokernel project outputs to the console.  It can be built and executed
on QEMU as follows:

    make qemu

---------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info
