Re: [U-Boot] Chain loading an u-boot from an u-boot

1. add option to 'go' command, which is hard as it has variable arguments

Theoretically I could use a u-boot image to encapsulate the second u-boot and use 'bootm', but I think I'll stumble over the same kind of questions.

There is already 'dcache off' but I wonder if something like 'go prepare' would be useful? Another option is that bootm has a prepare state, but it requires an image.

I agree with Simon. If you have not changed your target, you are using a MX31 and what cleanup_linux for arm1136 does is turning off the caches. What about if you turn off i-cache and d-cache in einem script before the go command ?
