[v2,0/2] remoteproc: mss: Improve mem_assign and firmware load

Message

Two things came up in the effort of figuring out why the modem crashed the
entire system when being restarted; the first one solves the actual problem, in
that it's not possible to reclaim the main modem firmware region unless the
modem subsystem is running - causing the crash.

The second patch aligns the firmware loading process to that of the downstream
driver, which seems to be a requirement in 8974 as well.

Bjorn Andersson (2):
  remoteproc: qcom_q6v5_mss: Don't reassign mpss region on shutdown
  remoteproc: qcom_q6v5_mss: Validate each segment during loading
