* Make sure HUSH is initialized for running auto-update scripts

* Make 5200 reset command _really_ reset the board, without running
  any other code after it

* Fix flash mapping and display on P3G4 board

* Patch by Kyle Harris, 15 Jul 2003:
  - add support for Intel IXP425 CPU
  - add support for IXDP425 eval board
