I consider psim and jmr3904 to be top tier BSPs even though they are
simulators.
jmr3904 has more failures but that's because some support like TLS is
missing
on the MIPS.

moxiesim and shsim (multiple variants there) should work but I don't
recall.

I would like to remove gdbarmsim. It has a lot of variants which increases
load on the RTEMS BSP Builder, it has not worked since some rework on
the ARM at least 2 years ago which didn't get done to this BSP, and
we have at least two ARM Qemu targets which are better.

IMO ARM simulator testing should ensure that Qemu for Zynq, realview,
and one of the STM variants works.

I have a script that I use on Centos, Ubuntu and FreeBSD to test a LOT.
It takes 18-30+ hours depending on the computer. Please make sure I
know if something gets added so I can add it to that script and results
begin to show up on the build results list.
