There is some support for switches in U-Boot (e.g. mv88e61xx) but no framework that I know of; and I suspect what is expected from the switch in U-Boot is that it does not hamper Ethernet operations, nothing more. for mv88e61xx, this is done through a fixed configuration. > Regards, > Bhupesh Amicalement, -- Albert. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
