This serie of patches speed up access time of MVEBUMMC driver
This is allowed by a fix in MVEBUMMC init status check inspired from linux MVSDIO driver. * Hardware weirdness. The FIFO_EMPTY bit of the HW_STATE * register is sometimes not set before a while when some * "unusual" data block sizes are used (such as with the SWITCH * command), even despite the fact that the XFER_DONE interrupt * was raised. And if another data transfer starts before * this bit comes to good sense (which eventually happens by * itself) then the new transfer simply fails with a timeout.
It allows about 10x to 40x faster access time transfer on SHEEVAPLUG MMC It may also fixes some SD types incompatibilities
