Subject[PATCH 0/9] Generic earlyconsole for ARC UART Driver

This series switches ARC UART from custom earlyprintk support to generic
earlycon (many thanks to Rob for doing that).

The motivation is to get rid of the early platform code, which in turn
would help consolidate the init code across several ARC platforms.

First 3 patches are general cleanup/refactoring, not necesarily related to

Also the ARC platform change (8/9) is bundled in to keep series bisectable
w/o timing hassles. However it can be dropped if tty maintainers deem so.

Please review.


Vineet Gupta (9):
serial/arc: use uart_console_write() helper
serial/arc: Refactor by referencing to uart_port where possible
serial/arc: Remove the workaround for legacy ISS
serial/arc: Use generic earlycon infrastructure
serial/arc: remove earlyprintk support and switch to earlycon
serial/arc: remove last remanants of platform data
serial/arc: inline the probe helper
ARC: [arcfpga] RIP early uart platform device stuff
serial/arc: Add DT based earlycon support
