I want to get rid of the device argument in all these calls.
So the the mmc read would becomes "mmc read [ram address] [mmc sector start] [sector num]"?
Right. That's what we use on other storage devices, too.
Right now, getting rid of all of those is a bit of a chore. Personally, I'd prefer if we did it in such a way that we still *can* provide the argument on the command line. In my personal experience, I far more often think verb, object, rather than the other way around. The way I did the mdio command for phylib, one could do either one:
mii device foo mdio read 0 0
or
mdio read foo 0 0
(and, as a side bonus, from then on, mdio read 0 0 will work, too).
Though I can't for the life of me remember why I left the device identifier as a simple integer.
My 2 cents, Andy
