Hello,
In SDHCI protocol, the 'Block Count Enable' bit of the Transfer Mode
register is used to control 's->blkcnt' value. This bit is not relevant
in single block transfers. Also, Transfer Mode register value could be
set such that 's->blkcnt' would not see an update during multi block
transfers. Thus leading to an infinite loop.
This patch set attempts to correct 'Block Count Enable' bit usage.
This series incorporates changes suggested in patch set v2:

Thank you.
