[U-Boot] [PATCH 3/4 v4] powerpc: keymile: Add a check for the PIGGY debug board

Heiko Schocher hs at denx.de
Fri Nov 21 08:29:40 CET 2008


Check the presence of the PIGGY on the keymile boards mgcoge,
mgsuvd and kmeter1. If the PIGGY is not present, dont register
this Ethernet device.

changes since v3 patch:
 - add comment from Gary Jeenejohn
   calling keymile_hdlc_enet_initialize () in board_eth_init ()
