This patch adds SBI direct memory access synchronize (DSYN)) extension

== Change Log

+=== Version 0.4-rc0
What's our policy of bumping up versions?
This extension is meant for SBI v0.4 based on discussion with Atish.

We will be soon freezing SBI v0.3.
Do we have policies, or planning/schedule of versions?

What is the version supposed to be used for?

Regards,
Bin
