RockPro64 booting w/ u-boot v2019-rc3

[mko]

Hi John,
I’m also trying to make a RK3399 board work, in my case I’m using the Rock Pi 4 which is raspberry pi form factor and much cheaper. 

For rockpro64, manu has already submit the uboot for it, it's sysutils/u-boot-rockpro64, and I just make a trivial change to rock pi 4 u-boot config, and  it u-boot’s fine into multi-user mode, then panic.

Here’s the related bug report

Bug 240541 - Generic kernel on Rock Pi 4 RK3399 board panic

Bug 240538 - Rock Pi 4 runtime time error panic: clknode_init_parent_idx: Invalid parent index 5 for clock sclk_sdmmc
