Hi Tomohiro,

Ok, I think you misunderstand the machines.py file. It is a hierarchical 
machine configuration file. Only leaf nodes are valid machine targets. 
This is indicated by a class setting "virtual = true".

eg:

class Machine:
    virtual = True         # this is a virtual level (ie not a target)
    ...

class arm(Machine):     # arm inherits Machine
    some arm generic config
    ...

class arm926(arm):   # arm926 inherits arm
    some arm926 specifc config
    ...

class myboard(arm926):   #versatile inherits arm926
   virtual = False      # ie a real target
   versatile config


so you can do  ./tools/build.py machine=myboard  ....
but you can't do  ./tools/build.py machine=arm

regards,
Carl
