[PATCH 0/3] remoteproc: Introduce wkup_m3_rproc driver

Hi,
This patch series adds a wkup_m3_rproc driver for TI AM335x SoCs.
This family of SoCs contains an ARM Cortex M3 coprocessor that is
responsible for low-level power tasks that cannot be handled by
the main ARM Cortex A8 so firmware running from the CM3 can be
used instead. This driver handles loading of the firmware and
reset of the CM3 once it is booted.

This patch was split off from v4 of the am335x suspend series,
found here [1]. I have pushed a branch based on v3.19-rc1
containing all dependencies here [2] for am33xx suspend
for a higher level view of the entire series of patch sets. This
series is required for a coming series "drivers: soc: ti:
Introduce wkup_m3_ipc driver" that boots this rproc driver and
handles the communication layer between the SoC and this remote
processor.

This patch set depends on series "couple of generic remoteproc
enhancements" by Suman Anna found here [3]. The driver expects to
load firmware am335x-pm-firmware.elf from /lib/firmware which is
found here [4].

Regards,
Dave
