Ping. Just checking if anyone got a chance to review this patch series.

> Subject: [PATCHv4 00/11] hw/arm: Adding Cortex-M7 Asymmetric
> Multiprocessing boot support for i.MX8MP
>
> 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
>
> Changes in v3:
>
> - Added a new patch for smp removal from test_imx8mp_evk.py.
> - Added a new patch to introduce IRQ splitting for i.MX8MP AMP interrupt
>   routing.
> - Added a new patch to rename FSL_IMX8MP_NUM_CPUS to
> FSL_IMX8MP_NUM_A53,
>   since M7 is being introduced now.
> - In GPR, parent_phases moved from global variable to class struct
> - M7 reset handling moved from the machine to SRC device model.
> - Added ITCM and DTCM memory regions to support zephyr firmware
> loading.
>
> Changes in v4:
>
> - Move independent MAINTAINERS, CPU renaming and functional-test
> cleanups to the beginning of the series
> - Created a separate patch for ITCM and DTCM modeling.
> - Move IRQ splitter infrastructure before Cortex-M7 integration
