[SRU][K][PATCH 0/1] enable CONFIG_SERIAL_8250_MID=y

[Andrea Righi]

BugLink: https://bugs.launchpad.net/bugs/2009283

[Impact]

CONFIG_SERIAL_8250_MID=y is required to properly use the serial console
on some platforms that are using the "mid" serial driver (such as some
Intel SoC platforms).

The generic kernel should build this driver statically to make sure we
properly support these platforms.

[Test case]

Boot the Ubuntu generic kernel on a system that is using the "mid"
serial driver (e.g, no PCI serial).

[Fix]

Enable CONFIG_SERIAL_8250_MID=y.

[Regression potential]

Kernel footprint is increased a bit with this change (around +9K), so we
may see little performance regressions at boot time in really small
platforms (additional memory usage is probably negligible), but it is
worth it, otherwise we won't be able to properly support these
platforms.

NOTE: we may want to disable this option in the could kernels and
derivatives and keep it only for the generic.
