Subject: Re: autoboot with initial RAM disk

(this really belongs on the ppcboot list...)

You can do arbitrarily complicated things in the ppcboot 'bootcmd'
argument.  In your case:

  setenv bootcmd tftp 100000 pImage\; tftp 300000 initrd\; bootm 100000
300000

If your bootcmd variable gets too long, ppcboot will complain - then you
just have to do something like:

  setenv bootcmd run first_half\; run second_half
  setenv first_half command\; command\; ...
  setenv second_half ...
