ARM: ux500: Enable the SMSC9115 on Snowball via Device Tree (bf76e062) · Commits · 戴 / test

Here we split the description of the external-bus@50000000 over two description files. In the more generic db8500 description file we only specify the external-bus. Normally this would be used to communicate with a NOR-flash device. On the Snowball however, the SMSC9115 Ethernet chip occupies it. In the Snowball board specific description file is where we actually specify that it is in fact the Ethernet device which lives here. Signed-off-by:
