Subject: [PATCH] Atmel MACB ethernet driver
This is a network device driver for the Atmel MACB interface, which
is present on the AT32AP7000 device from Atmel. I think it's basically
the same as the EMAC interface on AT91, so it should possibly be
merged with the at91_ether driver some time in the future. At the
moment, however, the at91_ether driver has quite a lot of at91-
specific dependencies so it's hard to reuse on AVR32.
This is basically the same patch as the one distributed with the
AT32STK1000 BSP version 1.0, converted to use platform_device and
struct clk instead of at32_device.
