Dear ksi@koi8.net,

As a matter of fact, SM501 is an older, now nonexistent version of SM502.
Yeah. Tell that to some hardware companies who are shipping boards with the SM501 on it. :-)
Its support in U-Boot is rudimentary. I'd rather removed that old sm501.c altogether and replaced it with a new sm502.c. That should work for old SM501 chips if there are still any in existence.
They are, and will be in existence at least for a couple of years (my expectation for couple is a two-digit number).
Support is much better in Linux kernel -- it is almost fully supported out of the box, video, USB, sound etc.
Linux is an OS - U-Boot is a mere boot loader ;-)
Best regards,
Wolfgang Denk
