This patch changes the static environment string compiled on the host. These is the default value that gets the board booting up. The environment variable memsize can be overwritten to 256M by the boards that have more memory. So, there is no hard limit. ...which I believe is better than kernel failing to load on old boards; leaving some users clueless about failure. Detecting the actual memory size and then changing the environment variable can be a feature, but it isn't fool proof, because many applications esp on DM3730, use memory hole and would like their bootargs to be different. ~sanjeev > > -- > Tom > _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
