For me even "rootwait" is sometimes too difficult to remember :-) What we (as in beagleboard.org) are currently doing is this: u-boot: http://gitorious.org/beagleboard-validation/u-boot/commit/70ed67cacbb1b7158e059b9b5d10308cce2d917a http://gitorious.org/beagleboard-validation/u-boot/commit/74f700341c656e1636221a53347caccbfc07c224 kernel: http://gitorious.org/beagleboard-validation/linux/commit/32fb278553a4cd6126c1791d70aa33df12f73d90 It's very ugly and needs a rethink before it can get posted to here, but it works great! The plan is to do this as part of the patchset to add support for the 37xx based beagleboardXM. regards, Koen-- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
