I think it's better to change the Makefile and leave the slightly odd Kconfig symbol name. Arnd

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.
