From 76880b08c4cf0e04332b17fd02bce0340289ccc2 Mon Sep 17 00:00:00 2001 From: Weijie Gao Date: Thu, 12 Nov 2020 16:35:56 +0800 Subject: mips: mtmips: add two reference boards for mt7620 The mt7620_rfb board supports integrated 10/100M PHYs plus two external giga PHYs. It also has 8MB SPI-NOR, mini PCI-e x1 slot, SDHC and USB. The mt7620_mt7530_rfb boards supports an external MT7530 giga switch and a 16MB SPI-NOR flash.
