[poky] PREEMPT_RT booting on atom-pc

[Darren Hart]

After finding the botched (by me) kernel config meta data for the
atom-pc-preempt_rt configuration, I was able to build and boot
linux-yocto-rt_stablegit on the N405 (Black Sand).

root at atom-pc:~# uname -r
2.6.34.7-rt-yocto-preempt-rt

root at atom-pc:~# cyclictest -l 20000
policy: other/other: loadavg: 0.86 0.34 0.12 2/70 515
T: 0 (  515) P: 0 I:1000 C:  20000 Min:     27 Act:   30 Avg:   51 Max: 641

root at atom-pc:~# cyclictest -q -l 20000
T: 0 (  517) P: 0 I:1000 C:  20000 Min:     27 Act:   29 Avg:   32 Max: 126

I wanted to be able to report a few more tests, but I'm having
some boot media issues I'll need to sort out. Obviously cyclictest
should be run with -f PRIO.

So, it boots, that's something. :-) I'll have more data to share
in the near future.
