The 8250_of never compiled since in the Kconfig we have SERIAL_OF_PLATFORM
but in the makefile we expect to have SERIAL_8250_OF...

In the Kconfig keep the SERIAL_OF_PLATFORM for compatibility reasons and
let it select the SERIAL_8250_OF. Later we can replace the
SERIAL_OF_PLATFORM use in defconfigs to SERIAL_8250_OF.

When the 8250_of.c is actually compiled we will have two errors:
missing linux/nwpserial.h and 8250/8250.h.
Fix those as well at the same time when enable the compilation of the
driver.

Hi,

this is fixes linux-next. W/o the patch davinci devices are not booting in DT
mode for example.

Regards,
Peter

Thanks for the report. Indeed this could not have worked.

This will still require changing all the defconfigs, as SERIAL_OF_PLATFORM
is a silent option now. I think it's better to change the Makefile and
leave the slightly odd Kconfig symbol name.
