From e35c343dd9c18d4d3e6424e2fab38f08085875d6 Mon Sep 17 00:00:00 2001 From: Philippe Mathieu-Daudé Date: Fri, 14 Aug 2020 11:23:43 +0200 Subject: hw/sd: Add sdbus_write_data() to write multiples bytes on the data line MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a sdbus_write_data() method to write multiple bytes on the data line of a SD bus. We might improve the tracing later, for now keep logging each byte individually.
