The grasshopper board is a neat avr32 evaluation kit produced by In-Circuit GmbH. See http://www.ic-board.de/product_info.php?info=p75_ICnova-AP7000-Base.html for detailed information about this device.
Signed-off-by: Andreas Bießmann biessmann@corscience.de --- changes since v1: - use vim: set noet ts=8 for 80 char per line checking - replace blank indention by tab indention - add board_early_init_r to explicitely set the phy address to 0x00
changes since v2: - add MAINTAINERS entry
