This patch enables EMAC on the DM365 EVM.
Signed-off-by: Sandeep Paulraj <s-paul...@ti.com>
---
Changes since v1 include using a memory map to manipulate GPIO registers.
This was suggested by Wolfgang.
When compiling with this patch DM365 will still give compilation issues as i
have
to send an update to the EMAC driver for DM365. Patch to follow.
