Passing boot logs to Linux?

[Csókás Bence]

Hi!

Is passing the U-Boot boot log to Linux supported yet? We are working 
with a third-party solution, which works, but is a bit hacky, so I was 
wondering if an official solution has been merged yet.

I saw that there was an option CONFIG_CONSOLE_RECORD that saves 
everything to a membuff, but I don't know if that can be exported to 
Linux yet. And if not in the tree yet, would such a patch be welcome?
