This patch enables EMAC on the DM365 EVM.

Signed-off-by: Sandeep Paulraj s-paulraj@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.

You may want to convert the constants from 0xffeffff -> ~(1 << 20) 0x0010000 -> (1 << 20) or bit = 20; (1 << bit) Up to you.

Fine otherwise. Tom
