Subject: [PATCH 0/2] mmc: sdhci: add quirk to disable bounce buffer

This patch series adds a new bit to quirks2 for disabling the bounce
buffer.  On some hardware, this is required for proper operation.  An
example of such hardware is the SDHCI controller of the Nintendo Wii's
"Hollywood" chipset.  Without this patch, the onboard Broadcom 4318
Wi-Fi fails to connect to any networks.

Patch 1 introduces the new quirk bit.
Patch 2 applies it to sdhci-of-hlwd.
