From: Jan Kiszka Date: Sat, 18 Sep 2021 06:17:52 +0000 (+0200) Subject: arm: dts: Add IOT2050 device tree files X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=c3a879510a0d49355408844a8fd942224568d48d;p=u-boot.git arm: dts: Add IOT2050 device tree files Prepares for the addition of the IOT2050 board which is based on the TI AM65x. The board comes in four variants, Basic and Advanced, each as product generation 1 (SR1.0) and 2 (SR2.x), so there are separate dts files needed. Furthermore, the SPL has its own device tree. Based on original board support by Le Jin, Gao Nian and Chao Zeng.
