This is why we need a discussion. For at least the arm, powerpc, and m68k,
there are a lot of BSPs and I have to believe some are no longer needed. I
don't want to kill any BSP that has an active user even if the hardware is
on
longer available.
Kinsey suggested we pick a minimum ARM level and use that as a first
cut at ARM BSPs. We need to be careful to consider space grade versions
of old CPUs though. And I do not want to purge that support from score.
For example, the m68k still has m68040 mvme* BSPs. Some
labs still have those. But the mrm332 for example, might be a good candidate
to remove. Strangely, https://robominds.com/ is still up and looks just
like it
did when I ordered the mrm332 OAR has. I don't think it has been out of the
box for almost a decade though. When we moved back then, the lab was
packed up and some boards are still in boxes.
