Subject: [RFC PATCH 0/2] mmc: sdhci: Add SDHCI_QUIRK2_BROKEN_SDMA_BOUNDARY_BUFFER

From: Srinivas Kandagatla <srinivas.kandagatla@...aro.org>

This patchset adds quirk to support cards which have issues when sdma
boundary buffer bits are programmed in Block Size Register (0x04)
when using ADMA.

First patch adds quirk and second one uses that quirk in msm sdhci driver.

Tested on DB410c with WLAN SDIO card.

thanks,
srini
