But we do have P1022DS board support, and my understanding is that part of the function of U-Boot is to prepare the board so that it can be used by Linux, or whatever OS it boots. Besides, there's tons of hardware that is not supported by U-Boot but must be initialized by U-Boot anyway. > Once there was a good old tradition that a driver in an OS makes sure > to initialize the hardware as it needs it for reliable operation.

Well, now we're talking about a very old issue that always raises disagreement -- exactly what should U-Boot be doing vs. Linux. And this is something that changes over time. For example, QE pin muxing used to be done in U-Boot, but now it's done in Linux. Well, except for the QE features that U-Boot uses. In that case, it's done in U-Boot *and* Linux. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
