The whole purpose of DM is somewhat defeated when we still need board specific initializations. Any ideas how we can get all boot messages without board specific inits? 'u-boot,dm-pre-reloc;' in the uart device tree node did not help.
You can put that in your serial driver, perhaps? Or in the initial SoC init code?
Another recent way (in -next) is to use events to monitor the EVT_DM_PRE_PROBE event for the serial driver.
It's just the same thing every single imx platform is doing.
