Hello Pierre,

currently sometimes the SD/MMC card inserted results in recognition failure on ARM Versatile board:

   <<<Plug in MMC card>>>

root@versatile:~# mmcblk0: mmc0:0001 SDMB-32 31360KiB
 mmcblk0:<3>mmcblk0: error 3 transferring data
end_request: I/O error, dev mmcblk0, sector 0
Buffer I/O error on device mmcblk0, logical block 0
mmcblk0: error 3 transferring data
end_request: I/O error, dev mmcblk0, sector 0
Buffer I/O error on device mmcblk0, logical block 0
 unable to read partition table

This patch fixes the problem.
