Ocotea:
- Add IBM PPC440GX Ref Platform support (Ocotea)
Original code by Paul Reynolds <PaulReynolds@lhsolutions.com>
Adapted to U-Boot and 440GX port
440gx_enet.c:
- Add gracious handling of all Ethernet Pin Selections for 440GX
- Add RGMII selection for Cicada CIS8201 Gigabit PHY
ppc440.h:
- Add needed bit definitions
- Fix formatting
* Patch by Carl Riechers, 1 Mar 2004:
Add PPC440GX prbdv0 divider to fix memory clock calculation.
* Patch by Stephan Linz, 27 Feb 2004
- avoid problems for targets without NFS download support
