Hi,

This series fixes loading a M4 firmware into memory and start that M4
core using bootaux on i.MX8MQ platforms.

There were two issues:
1- the memory where the firmware is loaded (TCM) wasn't mapped
2- the bootaux code relied on ulong instead of u32 (M4 core is 32-bit)

This was tested on Nitrogen8M platform.

Regards,
Gary
