From b02f76a83541fe9fe3a2918039b26fc133699c17 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 16 Aug 2018 15:27:30 +0200 Subject: mips: Add LinkIt Smart 7688 support The LinkIt Smart 7688 modules have a MT7688 SoC with 128 MiB of RAM and 32 MiB of flash (SPI NOR). 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.
