[Qemu-devel] [PATCH v2 3/3] sd: sdhci: Remove block count enable check in single block transfers |
Date: |
Wed, 8 Feb 2017 12:12:12 +0530 |
From: Prasad J Pandit <address@hidden>
In the SDHCI protocol the 'Block count enable' bit
of the Transfer Mode register is relevant only in multi block
transfers. We need not check it in single block transfers.
