Hi Erwin,

serial_atmel.c is an ancient,crappy serial driver for AT91 cpus. Later,
a driver has been written for the AT91RM9200 that uses the rather new
serial core driver (atmel_serial.c). The serial hardware for the
mmu-less AT91 cpus and the AT91RM9200 is a bit different, thus the
atmel_serial driver can't be used for the mmu-less AT91 cpus. I have
adapted the new driver for AT91x40 cpus, with some improvements so that
no overrun errors can happen with high transfer speeds.
Can you get these changes mainlined?
I have managed to get core at91x40 cpu support mainlined
(within the arch/arm/mach-at91).
Hi Greg,
this is great. At the moment, I don't have the time to clean up the
patch for inclusion, and currently it is for 2.4 only. I can send you
the patch for 2.4 as-is, if you like, but it's possible that it needs
some tweaking. I have sent the patch to Bob, maybe we get back a 2.6
port if we are lucky.
Yep, please send me a copy of it too.
If Bob doesn't get to it first I'll have a look at up-porting
the changes to the 2.6 kernel version of the driver.
Thanks
Greg
Although there is still
a couple of missing non-mmu peices in the arm code - I
expect these will get mainlined sometime in the not too
distant future. I would be good to have the atmel_serial.c
driver support in there too.
Regards
Greg

Hi all
appears the htdig is intermittent. Does anyone know the the reason for
the two serial drivers for Atmel. One is called serial_atmel.c the
other is called atmel_serial.c
