I talked with Wolfgang a little on IRC on this, and we didn't reach a conclusion nor come up with an alternative, but I guess the problem is we need to figure something out, now. We've hit a roadblock on "allow UART loading" and regret over keeping MMC+VFAT working. How bad are things going to get when patches pop up for USB (AM33xx ROM allows for RNDIS USB, iirc) ? Maybe we need to separate out the systems which are very resource constrained from the ones that aren't, share code where we can and make that code obviously marked as such. >> that has never been designed to run before relocation. > > At least some SPLs do relocation. Or don't need to exactly. -- Tom _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
