So changes are mainly,
1. Different capitalization of file names.
2. Different function names (sb800 vs. sb900).
3. Different comments.
4. Changes to the SB800 file which have not been ported to the SB900
file.
So looking at the lspci output,
00:14.5 USB controller: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 USB OHCI2 Controller
Linux drivers(?) seem to use the same code for SB7x0/SB8x0/SB9x0 too. So
I just assume that they are indeed very similar.
Should not we do the same? Especially because of item 4., that fixes get
ported to all generations.
If that is unfeasible at least spelling of filenames should be kept
consistent in my opinion.
Thanks,
Paul
