This patch is for testing i.MX8QXP patchset [PATCH V2 00/32] i.MX: Add i.MX8QXP support
https://lists.denx.de/pipermail/u-boot/2018-July/335079.html
The board is using B0 chip, A0 chip is not being supported.
Please help test if you are interested. I'll post out V3 after collecting
more comments.
Sadly, I do not know where to download scfw_tcm.bin in public for B0 QXP.

Thanks,
Peng.
