Blackfin arch: Add BF537-STAMP platform support for ENC28J60 SPI Ethernet MAC
This device shouldn't be considered as an alternative to a Memory Mapped or built-in Ethernet MAC. Throughput is slow (~460kByte/s) while generating a very high system load (~60%). Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
