Dear Vasily Khoruzhick,

In message <CA+E=qVeXE0wUtN4nb6k-zAH7uqVF4J0umd33+GXkQb3yPvTW+A@mail.gmail.com> you wrote:

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.

No, it's not so simple, but far more convenient.  And over time, much
more time-saving.

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

Best regards,

Wolfgang Denk
