[U-Boot] USB unaligned problem

[Daniel Hellstrom]

Hi Remy,

I experience unaligned exceptions when using the USB stack in u-boot on 
SPARC/LEON. I believe that there are many places in the code that must 
be updated since many structures are declared with the GCC attribute 
PACKED and still use 16-bit or 32-bit fields. However, I have so far 
only needed to patch one C-line to make it work. I'm not sure why the 
packed attribute is used in so many structures, I guess it is bacause of 
the layout of the USB information headers read from USB devices.

Please see commit 5b6bc53e4c3eadd04f2ecb94bbb596dca306236a in u-boot 
sparc repoistory, usb branch:

What do you think?
