Paul Walmsley 2bf22b3982 mmc: core: add workaround for controllers with broken multiblock reads ... Due to hardware bugs, some MMC host controllers don't support multiple-block reads[1]. To resolve, add a new MMC capability flag, MMC_CAP2_NO_MULTI_READ, which can be set by affected host controller drivers. When this capability is set, all reads will be issued one sector at a time. 1. See for example Advisory 2.1.1.128 "MMC: Multiple Block Read Operation Issue" in _OMAP3530/3525/3515/3503 Silicon Errata_ Revision F (October 2010) (SPRZ278F), available from http://focus.ti.com/lit/er/sprz278f/sprz278f.pdf Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Dave Hylands <dhylands@gmail.com> Tested-by: Steve Sakoman <sakoman@gmail.com> Signed-off-by: Chris Ball <cjb@laptop.org>		2011-10-27 09:10:57 -04:00
