Sriramakrishnan ad021ae886 TI Davinci EMAC : Abstract Buffer address translation logic.
When programming the DMA engine, the next pointers must be
programmed with physical address as seen from the DMA master
address space. This address may be different from physical
address of the buffer RAM area. This patch abstracts the
buffer address translation logic.

Sriramakrishnan 01a9af36cd TI Davinci EMAC : add platform specific interrupt enable/disable logic.
On certain SOCs, the EMAC controller is interfaced with a wrapper logic
for handling interrupts. This  patch implements a platform
specific hook to cater to platforms that require custom interrupt
handling logic

Sriramakrishnan 8ee2bf9ab7 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.
