* Patch by Paul Ruhland, 17 May 2004:

  - Add support for the Logic Zoom LH7A40x based SDK board(s),
    specifically the LPD7A400.

* Patches by Robert Schwebel, 15 May 2004:
  - call MAC address reading code also for SMSC91C111;
  - make SMSC91C111 timeout configurable, remove duplicate code
  - fix get_timer() for PXA
  - update doc/README.JFFS2
  - use "bootfile" env variable also for jffs2
