DM_SERIAL for i.MX6 Hummingboard/Cubox-i

[Baruch Siach <baruch@tkos.co.il>]

Hi u-boot list,

I am trying to migrate the Hummingboard platform to DM_SERIAL. See below
what I got so far. Booting this on top of master (as of commit
8bc87a4c5) shows nothing on the serial console. Next thing I plan to try
is toggle GPIOs in entry code to see how far the code proceeds.

Any idea where to look before I go down that way?

Thanks,
baruch
