Subject: [PATCH 1/3] TI Davinci EMAC : Re-use driver for other platforms.
The davinci EMAC peripheral is also available on other TI
platforms -notably TI AM3517 SoC. This patch modifies the
config option and the platform structure header files so that
the driver can be reused on non-davinci platforms as well.
