OpenEmbedded 
 OE for the Amida Simputer
 
 Adding a new device to OE
  is extremely easy
      in most cases, architecture / SoC support already there
  you just create a "conf/machine/foobar.conf" rule file
  content of the file
      size of root flash image
      which rootfs format to create (jffs2, ...)
      which kernel to build
      which compiler architecture + flags to use
  see following example for Amida 4200
