[00/11] remoteproc: stm32: Add support for synchronisation with MCU

Message

Mathieu Poirier March 24, 2020, 10:03 p.m. UTC

This patchset needs to be applied on top of this one [1].

It refactors the STM32 platform code in order to introduce support for
synchronising with an MCU that would have been started by another entity.

Most of the code is taken from work that Arnaud has already published [2].

On top of making sure the classic case where the remoteproc core is in
charge of the MCU's lifecyle is still functional, this set also tested that
it can synchronise with the MCU on ST's mp157c board. 

Thanks,
Mathieu
