UIO or remoteproc/rpmsg
Maybe best to wait a bit until there is clarity!!

1. It is said that for next SDK based on kernel 3.14 LTS, the
beaglebone community code and TI code will be pretty much aligned
for PRU. I want to know in which direction either in UIO driver
side or RemoteProc driver side, PRU software will be aligned ?
A: We are going the remoteproc/rpmsg route. I believe the plan is to
eventually phase out the uio driver completely, but to my knowledge
that process has not yet begun in earnest.
