Host USB on MPC8247

Host USB on MPC8247

[Uros Borovsak]

Hello,

I'm looking for host USB driver for MPC8247. We are using MV kernel 
2.6.10 and I'm wondering, if there is a driver for this specific kernel.

I'm aware of cpm2usb project on sourceforge, but it is for kernel 
2.6.13. How difficult would it be to patch only usb part of kernel from 
2.6.10 to 2.6.13 so I could use that drivers. I only need suport for USB 
storage devices, so that driver is enough for me.

Thanks,

Best regards,

Uros

Hello,

Can you at least give me some idea how difficult would it be to patch 
USB part of kernel from 2.6.13 to 2.6.10?

Are changes only in usb part of kernel, or are there also some changes 
in other parts of kernel, that I would have to port?

Thanks,

Best regards

As far as I know USB core undergone signifcant changes between 2.6.10 
and 2.6.13. Still it's hard to tell how difficult would it be to 
backport USB from 2.6.13 to 2.6.10.
Besides, it maybe worth upgrading your kernel instead of backporing USB 
to 2.6.10.

Thanks for reply,

I made a mistake while typing the message.

In reality I was asking how difficult would it be to port USB part  of 
kernel from 2.6.10 to 2.6.13, but I mixed kernel version's when typing.

Upgrading the whole kernel is not a way to go for me here, becouse 
company is using montavista kernel, and if I upgrade the whole kernel, I 
would have to port all their patches also.

I believe that MontaVista will use higher kernel version some time, so I 
wouldn't go backporting driver to 2.6.10, but I would prefer to port USB 
part of kernel from 2.6.10 to 2.6.13.

Do you think that is possible and how hard would it be?

USB subsystem is relatively stand-alone.  So, try replace the whole
drivers/usb/ directory and update usb related header files under
include/.

ps: the question is off-topic on powerpc list.
