From 3af3bebc215428aba3c7fd176d7f146045d51d68 Mon Sep 17 00:00:00 2001 From: Breno Matheus Lima Date: Wed, 10 Oct 2018 01:10:31 +0000 Subject: [PATCH] doc: imx: Move SPD related info to the appropriate doc Currently the Serial Download Protocol tools and procedure are documented in two places: - doc/imx/README.sdp - doc/imx/README.imx6 It is better to consolidate all SDP related information into README.sdp file, so move the content from README.imx6 to README.sdp.
