USB host on Freescale MPC880

USB host on Freescale MPC880

[Dayton, Dean]

I need to provide a USB host interface on a propietary board using a
Freescale (Motorola) MPC880. The MPC880 has a USB implemented in the
CPM, but I haven't found any Linux support for it. Can anyone point me
to existing drivers? Does anyone know of any problems that would/should
prevent me from using the MPC880's USB interface?

Thanks

Greetings Dean *list*.

There are some propiatery drivers... but... it's an oxymoron, to pay 
licensing fees for Linux... I'd sooner eat nails then use the propiatery 
offerings, to be quite honest, I'd have to quit my job before being 
associated with such a thing.

Right now the Freescale 870-885 has minimal support in Linux, but, I do 
have some patches for a 2.4.x which map out this family of chip's memory 
map as per the specification and I have a very primitive USB loopback 
tester working for this architecture. Said patches are not really ready 
for public consumption, not to mention only being usable on a 2.4.

A propiatery board being developed by my company wants USB host 
support... and I'm fairly confident I can do that... and hopefully I can 
get some serious development work done on this over the next three to 
four months and release a patch/(s) for public consumption.

I estimate it will take another four months to get USB host working 
properly and perhaps a month to get USB-device support working properly 
(touch wood on both counts), I'm not sure about the required development 
time on that to be honest... but, if I don't get it finished in time for 
our propiatery board, the powers that be in my company will use a 
propiatery Linux offering... and I'll have to resign on the grounds of 
being an Open Source Evangalist ! I need to eat/pay rent... so I really 
need to get this board + USB working. *grin*.

Are you guys planning on devoting any development effort to hardware 
support of this freescale part ? If so, would it be prudent to 
co-ordinate the development effort ?

I have a fairly hacked over version of the original USB host driver that
works for 87x/88x.

Are you interested?

Hmm... do you have handy sources available somewhere ?

I would be interested in seeing this code as well.

We have developed our board with MPC880 and we would like
to try to use 8xx USB host interface with kernel version 2.4.25.
I would like to ask you, if we could use your USB host driver
and if yes where it is possible to get it.

                        Best regards
