I think that was historically the reason (in OHCI), but I never investigated if less 'packed' attributes would be suitable as well. > Please see commit 5b6bc53e4c3eadd04f2ecb94bbb596dca306236a in u-boot sparc > repoistory, usb branch: > > http://git.denx.de/?p=u-boot/u-boot-sparc.git;a=commit;h=5b6bc53e4c3eadd04f2ecb94bbb596dca306236a > > What do you think?
