Linus Torvalds de9c9f86be This pull request contains:
- Some refactoring, cleanups and small improvements
   from Sjur Brændeland. The improvements are mainly
   about better supporting varios virtio properties
   (such as virtio's config space, status and features).
   I now see that I messed up while commiting one of Sjur's
   patches and erroneously put myself as the author, as well
   as letting a nasty typo sneak in. I will not fix this in
   order to avoid rebasing the patches. Sjur - sorry!
 - A new remoteproc driver for OMAP-L13x (technically a
   DaVinci platform) from Robert Tivy.
 - Extend OMAP support to OMAP5 as well, from Vincent Stehlé.
 - Fix Kconfig VIRTUALIZATION dependency, from Suman Anna
   (a non-critical fix which arrived late during the rc cycle).

Sjur Brændeland ec4d02d918 remoteproc: Add STE modem driver
Add support for the STE modem shared memory driver.
This driver hooks into the remoteproc framework
in order to manage configuration and the virtio
devices.

This driver adds custom firmware handlers, because
STE modem uses a custom firmware layout.
