From 4c216d7d2d29af6cbc231f772e90f23ab619f109 Mon Sep 17 00:00:00 2001 From: Duy Dang Date: Thu, 30 Aug 2018 10:40:11 +0700 Subject: rcar-gen3: README: Use Markdown formatting This commit edits README files to use Markdown formatting. There are also some modifications: - Removed dependency on meta-renesas itself in meta-rcar-gen3/README.md and meta-rcar-gen3/README.linaro - Added E3 SoC information to meta-rcar-gen3/README.md - Replaced core-image-x11 by core-image-minimal in README.md, this image is not maintained.
