The patch series introduces a few cleanups aimed at reducing code duplication in the console driver.
Originally, patches 2 and 3 were part of NS16550 emulator v3 series [1]. Patch 1 removes some code duplication for logging via conring facility. Patch 2 (see [2]) removes code duplication between __putstr() and the rest of the driver. It also introduces private flags to select console devices for printout which simplifies some code paths. Patch 3 (see [3]) adds conring_flush() to send contents of conring to all currently available console devices.
