There's a lot more needed to get mainline ATF up and running on RK3399:

* Only mainline ATF will be able to use correct console (UART0)
* bouncebuf needs to be aware of SD DMA not being able to copy to SRAM/PMUSRAM
* bouncebuf needs static buffer to address heap limitation
* bugfix in ITS generatorscript

I've already addressed all issues for SD card boot (Fedora boots fine).

If you want to test, you can use my ATF tree:

https://git.theobroma-systems.com/puma-u-boot.git/log/?h=puma-v2019.04-atf

Status for booting from SPI NOR is, that ATF will be branched to,
but then the board hangs. However, I haven't analyzed the situation
in detail yet.
