The following series implements basic board support for
the kmeter1 board from keymile, based on a MPC8360.
This series provides the following functionality:
- The board can boot with a serial console on UART1
- Ethernet:
UCC1 in RGMII mode
UCC2 in RGMII mode
UCC4 in RMII mode
UCC5 in RMII mode
UCC6 in RMII mode
UCC7 in RMII mode
UCC8 in RMII mode
following patch is necessary for working UCC in RMII mode:

- Flash accessed via MTD layer
On this hardware there is an Intel P30 flash, following patch
series is necessary for working with this hardware:
