[PATCH V2 23/30] imx: imx8: bootaux: Add i.MX8 M4 boot support

[sbabic at denx.de]

> From: Ye Li <ye.li at nxp.com>
> 1. Implement bootaux for the M4 boot on i.MX8QM and QXP. Users need to download
>    M4 image to any DDR address first. Then use the
>    "bootaux <M4 download DDR address> [M4 core id]" to boot CM4_0
>    or CM4_1, the default core id is 0 for CM4_0.
>    Since current M4 only supports running in TCM. The bootaux will copy
>    the M4 image from DDR to its TCML.
> 2. Implment bootaux for HIFI on QXP
>    command: bootaux 0x81000000 1
