* 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
