From 88dc40991494951015978b381bc37899fd9971d4 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 16 Aug 2018 15:27:31 +0200 Subject: mips: Add Gardena Smart-Gateway board support The Gardena Smart-Gateway boards have a MT7688 SoC with 128 MiB of RAM and 8 MiB of flash (SPI NOR) and additional 128MiB SPI NAND storage. This patch also includes 2 targets. One is the target that can be programmed into the SPI NOR flash and a 2nd target "xxx-ram" is added to support loading and booting via an already running U-Boot version. This allows easy development and testing without the need to flash the image each time.
