ok. It happened between 2013.04 and 2013.07 by the patch from Simon below.
I have to run now that's why I can't look what exactly it is wrong.

Thanks,

35fc84fa1ff51e15ecd3e464dac87eb105ffed30 is the first bad commit
commit 35fc84fa1ff51e15ecd3e464dac87eb105ffed30
Author: Simon Glass <sjg@chromium.org>

    Refactor the bootm command to reduce code duplication

    At present the bootm code is mostly duplicated for the plain 'bootm'
    command and its sub-command variant. This makes the code harder to
    maintain and means that changes must be made to several places.

    Introduce do_bootm_states() which performs selected portions of the bootm
    work, so that both plain 'bootm' and 'bootm <sub_command>' can use the
    same code.

    Additional duplication exists in bootz, so tidy that up as well. This
    is not intended to change behaviour, apart from minor fixes where the
    previously-duplicated code missed some chunks of code.
