2010-08-30U-boot: MMC update.Martin LUNDHOLM
MMC has been updated with several improvements. Primarily MMC performance has been improved by using assembler code for low level FIFO handling. Also some MMC functionality has been added, e.g. support for DDR and reliable write. Data and command delay times were incremented, otherwise hangups and timeouts were observed. Tested on HREF+ 1.1 V21 and HREF+ 1.1 V32 (Micron PoP). Following WP depends on this change (more reliable SD card write support): ST-Ericsson ID: WP264488 Change-Id: Ic92abffe1640aa9375b8d43a6b8522ca8296a368 Reviewed-on: http://gerrit.lud.stericsson.com/gerrit/4056 Reviewed-by: Michael BRANDT <michael.brandt@stericsson.com> Tested-by: Michael BRANDT <michael.brandt@stericsson.com>
