Driver for the Atmel MACB on-chip ethernet controller. This driver has been tested on the ATSTK1000 board with a AT32AP7000 CPU. It should probably work on AT91SAM926x as well with some minor modifications. Hardware documentation can be found in the AT32AP7000 data sheet, which can be downloaded from http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
