They weren't in the original email header, only in the commit log as Cc's. >> How about: >> >> bootz <kern addr> [<fdt addr> [<initrd addr> [<initrd size>]]] > > What about bootz <kern addr> <initrd addr>[:<initrd size>] <fdt addr> > > example: bootz 0x12000000 0x13000000:0x40000 0x14000000 > Sure.

Yes, but you already have to be aware of some commands which will change env vars. This has to be script-able to be useful. The only other way I see is adding a command to get the size of a file. Perhaps the ls commands when given a single file can do that. Rob >> >> Another idea is to prepend the u-boot image header on file loading.
