From ec5a19dd935eb3793e1f6ed491e8035b3d7b1df9 Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Fri, 6 Oct 2006 00:44:03 -0700 Subject: [PATCH] mmc: multi sector write transfers SD cards extend the protocol by allowing the host to query a card how many blocks were successfully stored on the medium. This allows us to safely write chunks of blocks at once.
