I don't see a README in here, I'm wondering what the details/requirements are around ARM Trusted Firmware and the build process, for this platform does it use the open ARM ATF, or is it similar to other platforms that early boot is proprietary and u-boot is just chain loaded? Something like the sunxi 64 bit readme [1] would be useful.
We are using ATF and use a dedicated package tool to generate the final image.
Then the boot flow is SPL->ATF/TEE->U-Boot->Kernel. I do not have much time to write that down now. You may get a very good user guide from NXP sw release, if you want to boot your board or else.
Regards, Peng.
Peter

patch: "power: pmic.h: include dm/ofnode.h" and "power: pmic/regulator allow dm be omited by SPL" is previously reviewed in mailist to not merged. Pick it up.
The board support is a large patch because of the ddr related code. If it is not good, please first review/pick-up other patches if they are ok.
