There seems to be something amiss with cnosole output in today's release
(at least on my ppc qemu boot tests).
The console output seems to be back today. I assume its repair had
something to do with commit

>> hi Stephen，
Thanks for the info, Could you share more details about the issue you met? is it about early console print issue?
Here is the diff between my boot logs:
thanks, I checked the log, Can I understand it as you missed some early bootup log when use new release?
yes, the console messages stopped for a while when we switched from the
bootconsole to the final hvc0 console.
thanks, it makes sense, this commit broken the early console mechanism,
I will submit the fix patch for reviewing soon.
