From f24b56cbcd9d39cb2ed45b4b451f8614f9494c17 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 30 Oct 2013 17:55:09 +0100 Subject: [PATCH] ARM: kirkwood: add support for OpenBlocks A7 platform The OpenBlocks A7 board is designed and sold by PlatHome, and based on a Kirkwood 6283 Marvell SoC. It is quite similar to the OpenBlocks A6 already supported in the kernel, with the following main differences: - The A6 uses a RTC on I2C, while the A7 uses the internal SoC RTC. - The A6 has one Ethernet port, while the A7 has two Ethernet ports - The A6 has only one USB port, while the A7 integrates a USB hub, which provides two front-side USB port, and an internal USB port as well. - The A6 has 512 MB of RAM, while the A7 has 1 GB of RAM. - Slightly different GPIOs for some functions.
