[PATCH] Backport of development SPI SD-card patches to RTEMS 4.10.

[Pavel Pisa]

Hello Sebastian,

the patch is backport of the actual RTEMS GIT SD-card on SPI
implementation to the RTEMS 4.10.x-git. The following
RTEMS 4.10.99-git patch applies cleanly to the backport.

[PATCH v2] SPI SD-Card: setup valid CRC-7 for STOP_TRANSMISSION command.

The backport has been tested on MXS/CSB336 and we intend to use it
in the production setup after regular full testing and I would
provide feedback and fixes if there is some problem found.

I left on your taste if this should go into official RTEMS 4.10.x

Best wishes,

               Pavel
