From: Stefan Roese Date: Tue, 20 Oct 2015 13:14:47 +0000 (+0200) Subject: arm: mvebu: Add SolidRun ClearFog Armada 38x initial support X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=0299c90f396c5b2971a4bac596339f4b03661c27;p=u-boot.git arm: mvebu: Add SolidRun ClearFog Armada 38x initial support This patch adds basic support for the SolidRun ClearFog Armada 38x based board to mainline U-Boot. Supported interfaces / devices are: - DDR3 - UART - MMC - Ethernet port 0 (connected to dedicated PHY) - I2C The included DT source was taken from Russell King's ftp server: http://www.home.arm.linux.org.uk/~rmk/clearfog/ With only minor modifications, like the addition of some aliases and the "u-boot,dm-pre-reloc" property.
