This patch adds basic support for the Marvell Armada 3700 DB-88F3720 development board. Supported are the following interfaces: - UART - SPI (incl. SPI NOR) - I2C - Ethernet Signed-off-by: Stefan Roese <sr@denx.de> Cc: Nadav Haklai <nadavh@marvell.com> Cc: Kostya Porotchkin <kostap@marvell.com> Cc: Wilson Ding <dingwei@marvell.com> Cc: Victor Gu <xigu@marvell.com> Cc: Hua Jing <jinghua@marvell.com> Cc: Terry Zhou <bjzhou@marvell.com> Cc: Hanna Hawa <hannah@marvell.com> Cc: Haim Boot <hayim@marvell.com>master
