From: Stefan Roese Date: Wed, 25 May 2016 06:21:21 +0000 (+0200) Subject: arm64: mvebu: Add Armada 7K db-88f7040 development board support X-Git-Tag: KARO-TXSD-2017-03-15~42^2~3 X-Git-Url: https://git.kernelconcepts.de/?p=karo-tx-uboot.git;a=commitdiff_plain;h=6f8c2d49060a30cda2ea73e93ce0f882f732754f arm64: mvebu: Add Armada 7K db-88f7040 development board support This patch adds basic support for the Marvell Armada 7K DB-88F7040 development board. Supported are the following interfaces: - UART - SPI (incl. SPI NOR) - I2C - USB - SATA / AHCI Support for other interfaces will follow.
