RE: mpc8xx memory mapped 16550 extrenal uart driver

You can do the mapping anywhere you want, anywhere you do specific board
initialization is a good spot.  Check out
arch/ppc/platforms/sandpoint_setup.c
arch/ppc/platforms/sandpoint_serial.h
for an example on setting up the serial device.

Hi Steven,
Thanks for the quick reply. I did look at serial.c, however, i did not find
where do we map the device to the memory i.e. where are we doing chip select
setting and stuff. I saw that being done for CONFIG_SERIAL_TTTECH. Is that
what you are referring to or I am missing the point completely?

Lokesh

It's already in there.  drivers/char/serial.c

Hi gurus,

Does anybody know of a driver for an external 16550 memory mapped uart
driver for an mpc855 based board? Any help is appreciated?
