[Qemu-devel] [PATCH 2/2] sd: sdhci: block count enable not relevant in single block transfer

[P J P]

From: Prasad J Pandit <address@hidden>

In SDHCI device emulation the 'Block count enable' bit
of the Transfer Mode register is only relevant in multi block
transfers. We need not check it in single block transfers.
