Oops.  No, I cannot apply this.  When I enable  CONFIG_CMD_EXT4  in a
board config file, I get this:

+ ./MAKEALL TQM860L

It seems this happens when you only enable CONFIG_CMD_EXT4, without
explicitly enabling CONFIG_CMD_EXT2 as well.  Please fix this - if the
ext4 code needs ext2, then it should automatically enable this option.

Hm... How much code duplication (for ext2 and ext4 commands) does this
cause?

Best regards,

Wolfgang Denk
