Q: Does mainline Linux even boot on the DK?

A: No, it doesn't.

Yes, i saw that it was booting out of mainline.
Both DK01 and DK04 boards boots out of mainline.

cat /proc/version
Linux version 4.16.0-rc6 (srichara@srichara-linux) (gcc version 6.3.1 20170109 (Linaro GCC 6.3-2017.02)) #1677 SMP PREEMPT Wed Mar 21 12:58:14 IST 2018

If it does not boot for you, then can you check if your bootloader is passing this bootarg ?

bootargs=console=ttyMSM0,115200n8

This is the only one required from bootloader to boot.
That said, there should have been a default 'chosen' node in DTS
for the serial console atleast which is not there today. I will add this
in my v4 along with other changes.

Please add the missing basic board support before hacking random stuff
into the DTS.
