Sricharan R	a7df9dfcfd	rpmsg: glink: Return -EAGAIN when there is no FIFO space ... The TX FIFO can be full, if the remote client has not read enough data (or) reading it slowly. So its nessecary to return -EAGAIN to the local client to enable retry.

Bjorn Andersson	7339859da8	rpmsg: glink: Allow unaligned data access ... Glink protocol requires that each message is aligned on a 8 byte offset. This is purely a restriction from glink, so in order to support clients which do not adher to this, allow data packets of any size, but align the head index accordingly, effectively removing the alignment restriction.
