No, it's not clear what it is. I'd rename "init" to "setup", adding an AF argument. So I can setup it as AF2, or as GPIO-OUT, or whatever. > (There, we could also unset the marker, that this pin is no longer used > for gpio ...) No, I wouldn't like the marker. It's a boot loader, it shouldn't overdo sanity checks. Most of the times it runs the same "bootcmd" over and over. In the rare but important case it's a debugging tool, it shouldn't force policy, in my opinion (I already have problems with the kernel gpiolib, that doesn't let me fix mishaps at will). > Also, a board can have more then one gpio adapter, how we address > such a case? As Wolfgang suggested, we don't. If atmel calls it PORTC-12 I have no problem calling it gpio-76 by concatentating the ports as 0..31, 32..64, ... It's still better to have a gpio command than doing "mw <addr> <val>" over and over. In my old-fashioned way, it should be as simple as possible, but no simpler. /alessandro _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
