The Davinci EMAC peripheral is also available on other TI platforms -
notably TI AM3517 SoC. The following series of patches modify the driver 
suitably to make it platform agnostic.

This patch has been generated against the tip of linux-davinci git.

Sriramakrishnan (3):
  TI Davinci EMAC : Re-use driver for other platforms.
  TI Davinci EMAC : add platform specific interrupt enable/disable
    logic.
  TI Davinci EMAC : Abstract Buffer address translation logic.

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.

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

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.
