/* RPC layer types.. these define the payload of messages between IPUMM
 * and MPU.  This should be kept in sync between firmware build and
 * driver.
 *
 * TODO: xxx_control(XDM_GETVERSION) is a bit awkward to deal with, because
 * this seems to be the one special case where status->data is used..
 * possibly we should define a special ioctl and msg to handle this case.
