        First commit of adoptet bootloader

The main differences from original commit:

    * rebased over v2011.06 (original over v2010.12-rc2);
    * drop generated files;
    * don't drop dm365-unrelated files (original commit drops
      all MIPS, i386 etc files);
    * drop cmd_lcd_cmds;
    * move uflash tool into sepate commit.

This commit has to be cleaned and splitted in the future.
