Information on software I/F to use SDMA ROM script is not found
in "I.MX 7 Dual Applications Processor Reference Manual, Rev. 1, 01/2018"(IMX7DRM.pdf)
Specifically, there is "There is a description in Appendix A" as below,
but in practice the following chapter does not exist.
7.2.4.7 Software Interface Appendix A fully describes the SDMA Application Programming Interface (API).

I also checked the community but I can't find any official materials
The sample code Imx-sdma.c and sdma-imx7d.bin cannot be diverted and must be created by yourself.
