AM62P: AM62P dual boot requirement

Part Number: AM62P

Hi, 
Currently I am working on AM62P chipset.

My requirement is:

• MCU R5 firmware should boot from OSPI flash
• Linux on A53 should boot from eMMC

On power-up, the expected boot flow is:

ROM → SBL from OSPI → MCU R5 application startup → boot Linux on A53 from eMMC

From my understanding, the default MCU+ SDK SBL examples mainly support booting all components from a single boot media.

I would like to know:

1. Is this mixed boot flow (R5 from OSPI and Linux from eMMC) officially supported on AM62P?
2. What changes are required in SBL/U-Boot configuration to achieve this?
3. Is there any reference implementation or example available for this use case?

Any guidance would be helpful.
