In 512B disable emulation patch, a check is done to ensure that size
of the data is multiple of 4KB. However, the check is done with
brq->data.blocks, which is not initialized at the point of check.
This is now changed to blk_rq_sectors.

Add a new flag of SDHCI_NEEDS_RETUNING_TIMER to represent if the host
needs retuning timer currently when driving the card inserted.
This flag is set when the host does tuning the first time for the card
and is used afterwards whenever needs to decide if the host is currently
using a retuning time
Some of the host settings are affected by different cards inserted, e.g.
when an UHS-I card is inserted, the SDHCI_NEEDS_RETUING flag might be
set when the tuning timer expired and host's max_blk_count will be
reduced to make sure the data transfer for a command does not exceed 4MiB
to meet the ret
The following 2 patches fixed a bug related the tuning stuffs and
refactored the code to make it simpler and easier to read and understand.

This patch adds packed command feature of eMMC4.5.
The maximum number for packing read(or write) is offered
and exception event relevant to packed command which is
used for error handling is enabled. If host wants to use
this feature, MMC_CAP2_PACKED_CMD should be set.

Hi Seugwon, Saugata,
Here the actual large sector size support had one issue and anyway as of now
large sector size is not supported on any of the eMMC4.5 devices, whereas
the packed commands are already supported on eMMC4.5 chips so I would prefer
not to hold this patch for issue which is really
Looks good to me.

There are a number of MMC patches from me outstanding for 3.6.

latest versions are and in which order they should be applied - would you
