[U-Boot] PPC4xx: usbdev.c used at all?

[Stefan Roese]

Hi Marri,

I just "touched" the file "arch/powerpc/cpu/ppc4xx/usbdev.c" again to remove 
some GCC 4.6 compiler warnings. While doing this I wondered (again) if anybody 
is using this "driver" at all. I definitely never did. And I'm wondering if 
this code is useful at all.

So Marri (or anybody else): Do you need this driver in U-Boot?

If not, I'll just remove it in a short while.

Thanks.

Best regards,
Stefan

This code is used when usb device is used as boot medium for Linux.
Let me check what are the errors you are seeing.
Thanks,

Yes, please explain in more detail what exactly you mean with "boot medium for 
Linux". How does this work?

Best regards,

Please explain this in more detail. I fail to see, how this driver could be of 
any used. I definitely never used it. So please explain how exactly you make 
use of this driver, or why it is needed?

Best regards,
Stefan

I'm not willing to wait any longer.  I want to see these warnigns
fixed.

I'll pull your patch directly.

Rup, if you can explain that this driver is needed,, then please feel
free to submit a patch to re-add it - after cleaningup the warnings it
cuases, that is.

Thanks.
