The state-of-the-art has advanced in the rtems.git tree since these
projects happened, and it is not all documented. The ARM in particular
generally uses a static initialization or boot-time initialization of
the MMU. You  should study how the ARM approach works in the RTEMS
main repo, and consider whether that approach can be adopted by other
architectures/BSPs, how to improve that approach, and how to build
higher-level services on top of the low-level BSP support that exists.

One of the main interesting applications is to provide thread stack protection.

I can't speak to the WiFi support, maybe others know. But to get
started you would need to at least demonstrate that you have the
necessary hardware to succeed and that you can at a minimum boot/run
BBB with libbsd, and probably we should like you to show that you can
generate patches for libbsd.

I'm not certain if there is sufficient work/interest/mentoring available to support multiple BBB projects. You might consider what specific projects would interest you though. You should take a look at past years' GSoC projects documented on our wiki, they are linked from our main 'GSoC' page.

The most important aspect about doing development with a BBB is that you can use the JTAG, which requires some soldering and additional effort to work with a standalone JTAG debugger.  If you don't have that, and want to work with the BBB, it is highly recommended.
