From 655d216af952cc895269fbe7c628a255ccd3ceee Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Tue, 30 Apr 2019 09:39:25 +0200 Subject: [PATCH] README: davinci: update the documentation for DaVinci The DM* family of SOCs is no longer supported. We now support the omap-l138 lcdk board and Lego EV3 platform. Reflect those changes in the README.
