Hello,
I am trying to understand why Linux is doing it. Do you expect all
U-Boot version to do it?
It's because Linux doesn't really trust u-boot and initializes every
thing again ?
You don't know the state of the UART once you left U-boot. For
earlyprintk this may not be a big deal (they are for debugging only).
Mainline U-boot does it but that may also not required since ATF does it for us.
What I wanted to check is whether there are U-boot out configuring
"incorrectly" the UART for earlyprintk. But I guess we can leave that
aside for now.
