New Revision: 248809
URL: http://svnweb.freebsd.org/changeset/base/248809
Log:
Fix the AR933x platform device start/stop code.
This was ported from the AR724x code and I think that also doesn't
quite work. I'll investigate that soon.
With this in place the system reset path works, so 'reset' from kdb
actually resets the SoC.
Tested:
* AP121 test board
