As you could see from our internal maillist, Jacky has posted out i.MX8MM the
Restricted DDR code for review today. i.MX8MQ ddr code restructure is his next step. After Jacky done
that internally, the ddr and board code will be posted out to community.

I understand the ddr part block i.MX8MQ support in community for months.
But i.MX8QXP is totally different new architecture and it does not have the ddr code issue.
Also the scfw part has been restructured in the patchset v2.

Please consider reviewing the patchset

Currently there is no public available code for atf and scfw, so
There will no link in the README, I could only add steps
on how to build out images. Is this ok?

Still not. I have been working on other areas in the past days.
Hope I could port imx-mkimage to uboot.

Thanks,
