[U-Boot] [PATCH V3 0/4] drivers/sandbox: Introduce a simplified remoteproc framework

[Nishanth Menon]

Many System on Chip(SoC) solutions are complex with multiple
processors on the same die dedicated to either general purpose of
specialized functions. Many examples do exist in today's SoCs from
various vendors. Typical examples are micro controllers such as an ARM
M3/M0 doing a offload of specific function such as event integration
or power management or controlling camera etc.

Traditionally, the responsibility of loading up such a processor with
a firmware and communication has been with a High Level Operating
System(HLOS) such as Linux. However, there exists classes of products
where Linux would need to expect services from such a processor or
the delay of Linux and operating system being able to load up such a
firmware is unacceptable.

The intent here is to introduce a simplified remoteproc framework
which can then be used to provide basic services to these remote
processors.

Special thanks to Simon in helping cleaning up the series to a much
more better implementation.

The series is based on:
