[Developer] About support of the arm926ej-s

[Tomohiro Kitamura]

  Hi Carl
 
  Thank you for your reply.
  I understood my mistake and tried to execute correct machine option.

   ./tools/build.py machine=vast926e_x1 project=iguana wombat=true

  But, build didn't work well.
  At first I can't find serial_driver "l4_kdb".
  I corrected this.  from "l4_kdb" to "drv_l4_kdb".
  I think that it is not important problem.

  Still, I could't make image for compile error.
  According to my investigation gcc can't find "vast" platform in 
"./pistachio/platform/" .
  Does that mean I make "vast" platform myself to refer "pxa"?
