      mmc_spi: speedup for slow cards, less wear-out · 5cf20aa5
      Wolfgang Muees 提交于
      Speedup for slow cards by transfering more data at once.
      This patch also reduces the amount of wear-out of the flash
      blocks because fewer partial blocks are written.

      mmc: mmc_rescan detects card change in one run · 94d89efb
      Jorg Schummer 提交于
      With this patch, mmc_rescan can detect the removal of an mmc card and
      the insertion of (possibly another) card in the same run. This means
      that a card change can be detected without having to call
      mmc_detect_change multiple times.
      
      This change generalises the core such that it can be easily used by
      hosts which provide a mechanism to detect only the presence of a card
      reader cover, which has to be taken off in order to insert a card. Other
      hosts ("card detect" or "MMC_CAP_NEEDS_POLL") each receive an event when
      a card is removed and when a card is inserted, so it is sufficient for
      them if mmc_rescan handles only one event at a time. "Cover detect"
      hosts, however, only receive events about the cover status. This means
      that between 2 subsequent events, both a card removal and a card
      insertion can occur. In this case, the pre-patch version of mmc_rescan
      would only detect the removal of the previous card but not the insertion
      of the new card.
