[PATCHv2 0/7] hw/arm: Adding Cortex-M7 Asymmetric Multiprocessing boot support for i.MX8MP

Posted by Gaurav Sharma 2 weeks, 5 days ago

Changes in v1:

This series adds Asymmetric Multiprocessing (AMP) boot support for
the Cortex-M7 core on the i.MX8MP SoC. The M7 firmware can be loaded
and started from Linux running on the Cortex-A53 cores via the
remoteproc framework.

The series introduces the following peripheral models needed for AMP:
  - GPC (General Power Controller)
  - GPR (General Purpose Registers)
  - SRC (System Reset Controller) authored by Bernhard Beschow <shentey@gmail.com>
  - MU (Messaging Unit)
  - Extends the CCM with M7 clock outputs and wires into the i.MX8MP SoC
  - Enable Cortex-M7 boot in i.MX8MP EVK functional test

Changes in v2:

- Removed the usage of device_class_set_legacy_reset in imx8mp gpc,gpr,mu and
  src.
- Removed the usage of 'smp' , 'maxcpus' and 'enable-cm7' to make the
  invocation simpler.
- Cleaned up imx8mp_src by removing redundant/unused code.
- Updated Maintainers and improved the imx8mp documentation
