Thanks for the reply. I've taken a look at the arch folder, and it gives me
an initial indication of the effort required to port to the ARM Cortex A9
processor.

Im not sure if I want to attempt this, because I feel the return on investment
would be low, since there is no supporting eco-system, in terms of driver
support for various peripherals (graphics, lcd display, hdmi display, etc).

I can just see support for a console output using a COM port, and a
realtek ethernet driver.

It's going to be more work than just the processor architecture support,
one has to also invest time in building the eco-system around it, for
specific platforms in terms of bsp support.

Speaking from an RTEMS perspective, the various *BSD trees are great

sources for driver code that should be licensed appropriately for Pok.

It is also possible that the RTEMS source tree would be able to offer some

help here.

Just depends on what ARM SoC you are looking at. Getting even the

basics in with a COM port would be a great addition.
