[PATCH 0/2] Add a MicroBlaze remoteproc driver and binding

[Ben Levinsky <ben.levinsky@amd.com>]

This series adds initial remoteproc support for AMD MicroBlaze soft
processors.

The binding models the MicroBlaze remote processor as a child node whose
reg property describes the executable firmware memory window in the
MicroBlaze-local address space. The parent bus ranges property provides
the standard devicetree address translation to the Linux-visible system
physical address.

The driver uses that translated memory window as the executable
remoteproc carveout and coredump segment, holds the MicroBlaze in reset
through an active-low GPIO until firmware loading completes, and allows
the firmware image to be selected with the optional firmware-name
property. Firmware images without a resource table are also accepted.

This initial series focuses on basic load/start/stop support for a
single executable memory window. It does not add any transport or
mailbox integration.
