Yeah, I have added a sentence to the other one. Maybe also add a select? > Do you plan to add the actual tty driver soon? If not, maybe > only add one Kconfig symbol for the earlycon support. So, I completed the driver the weekend and can see the full console output, but there are still output glitches, possible locking issues up to RCU stalls and soft lockups, and only stubbed out baudrate support. Therefore I would rather keep the full driver as follow-up RFC in v2, unless I get it fixed during Hackweek. In the earlycon I am confident, and the only Kconfig change then is to switch from bool to tristate and to drop the newly added sentence again.
