At present the pinctrl nodes are not enabled in pre-relocation U-Boot so the UARTs do not correctly select the pinconfig to enable the UART pins. Fix this so that the U-Boot banner is printed.
This fixes serial output on rpi_3b_32b with the following config.txt options:
enable_uart=1 gpu_freq=250

Any thoughts on this series? At present all my lab tests fail.
I don't know if the problem is my firmware is too old (and so works) or your firmware is too old (and so fails) or if there's some phase-of-the-moon problem. So while I'd like to know _why_ my 3B is fine and yours is not, we should just take this I suppose.
I agree with Tom, we should try to find out what's the problem. Do you know which version (e.g. git commit or which version of rasbian etc) of the RPi FW you are using? If not, can you provide me with the md5sum's so that I can try to reproduce this.
