Accessing physical registers in A53 using linux commands

[subhash_ponnusamy]

Hi NXP team,

 I'm using I.MX8MMINI EVK for my project. I need to transfer data from M4 to A53 using message unit.

In A53 I need to access a physical register address (0x30AA0010) to see whether I received data or not.

How can I access this register through linux commands.

How should I transfer data from M4 to A53 through messaging unit (MU).

Regards,

Subhash
