This is a misconception. Experience on this very mailing list has shown that an extremely high number of issues is cause by incomplete and/or incorrect memory initialization. This is why U-Boot (be design!) makes sure we have a full C environment when doing this taks, where we can use printf() and friends for useful output etc. > It's not as simple as previous solution, isn't it?

We respect your personal preferences. But in this case we ask you to stick with the U-Boot design andimplement as requested. Thanks.
