powerpc/83xx: Add support for MPC8377E-WLAN boards
Anton Vorontsov [Fri, 24 Jul 2009 21:42:17 +0000 (01:42 +0400)]
MPC8377E-WLAN are basically RDB boards except:

- RAM extended to 512 MB;
- NAND flash removed, NOR flash extended to 64 MB;
- Vitesse VSC7385 5-port switch removed, RTL8211B PHY added;
- Power management MCU removed;
- PCI slot removed, another mini-PCI slot added (IRQ routing changed);
- USB3300 PHY's ID pin grounded, thus USB port is host-only.
