From da0189af1ee53b7ecf9f6a34e0fd69b3b064849e Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Fri, 24 Sep 2021 14:24:37 +1000 Subject: [PATCH] Add support for QMTech Wukong v2 board For now only the V2 of the board (slightly different pinout) and only the A100T variant. I also haven't added GPIOs or anything else on the PMODs really.
