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.
