[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Define the Condor/V3HSK board dependent parts of the RPC-IF device node.
Add device nodes for Spansion S25FS512S SPI flash and MTD partitions on it.

Based on the original patches by Dmitry Shifrin.

Changes in version 2:
- removed the "renesas,rpc-mode" prop from the RPC-IF device nodes;
- lowercased the hex numbers in the "reg" props and the <unit-address> parts
  of the node names;
- removed the leading zeros from the <unit-address> parts of the node names;
- refreshed the patch.
