So, I repair my second board (same as first, but with real 512M of SDRAM). Works, but of course memory is fixed at 256M. Tomorrow I will test current 2013.04 on this board since probably problem appears only on 256M-version. Currently I think about return fixed table of memory in the board file or get memory size by testing memory. In both cases we need to disable ESDCTL module and now I do not know how make it better rather than simple remove this module from Makefile.
