Did you test this change?
I remember rk3188 having issues (aka hanging) when trying to print
strings through the debug uart and only printch working at all.
(Timer issue or so?) ... Not sure if this got fixed in the meantime?
But you are using the debug uart for "production". Please use the
proper driver.
You may either properly setup normal uart or buffer the console output
until the uart is configured by device model (DM).
Here, we just use it for debug print, and the sram size is limited to
use more complex driver at spl stage.
I don't know there was a issue, but i test it on the Radxa board
today, it looks okay.
