ARM: bL_switcher: add a simple /dev user interface for debugging purposes
Only the basic call to aid debugging.
*** NOT FOR PRODUCTION ***
Usage:
echo <cpuid>,<clusterid> > /dev/b.L_switcher
where <cpuid> is the logical CPU number, and <clusterid> is 0 for the
first cluster and 1 for the second cluster.
