I worked on converting this patch to using the existing DDR setup functions: https://pastebin.com/6PGx0pMx
However I do see instability: after lauching the kernel I see a hang after "Starting the kernel..." sometimes.
The original DDR configuration that I used from Technexion in the original patch is very stable and never hangs.
The DDR iomux function can be used, but the mx6_dram_cfg() is the one that gives trouble.
I sent a v5 where I use the existing mx6dq_dram_iocfg() and a custom spl_dram_init_imx6qp_lpddr3() for the DDR timings.
Hopefully it is a little bit better :-)
