mpc83xx: add support for the MPC8360E-RDK
This is MPC8360E based board with:
- 256MB fixed SDRAM;
- 8MB Intel Strata NOR flash;
- StMICRO 64MiB NAND flash;
- two 10/100/1000 ethernet ports connected via Broadcom
BCM5481 PHYs;
- two 10/100 ethernet ports connected via National
DP83848 PHYs;
- one PCI and one miniPCI slots;
- four serial ports (two NS16550-compatible, two UCCs);
- four USB ports working through MPC8360E "FHCI" USB controller;
- Fujitsu MB86277 graphics controller;
- Analog to Digital Converter/Touchscreen controller, AD7843
connected to SPI.
Features not supported in this patch are:
- StMICRO 64MiB NAND flash (patch sent);
- MINT framebuffer initialization (patch is pending);
- Fetching production information from the EEPROM via I2C;
- FHCI USB;
- Two slow UCCs used as RS-485 UARTs.
