[Qemu-devel] [PATCH 0/2] sd: sdhci: correct transfer mode register usage

[P J P]

From: Prasad J Pandit <address@hidden>

Hello,

In SDHCI emulation, the 'Block Count Enable' bit of the Transfer Mode
register is used to control 's->blkcnt' value. One, this bit is not
relevant in single block transfers. Second, 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.

Thank you.
