+This patch fixes SDHCI CRC errors during of RX throughput testing on
+BCM4329 chip if SDIO BUS is clocked above 25MHz. In particular the
+checksum problem is observed on NVIDIA Tegra20 SoCs. The good watermark
+value is borrowed from downstream BCMDHD driver and it's matching to the
+value that is already used for the BCM4339 chip, hence let's re-use it
+for BCM4329.

+
+The chip ID was already printed out at the time when debug message about
+the changed F2 watermark is printed, hence let's drop the unnecessary part
+of the debug messages. This cleans code a tad and also allows to re-use
+the F2 watermark debug messages by multiple chips.

+
+Setting F2 block size to 128 bytes for BCM4329 allows to significantly
+improve RX throughput on NVIDIA Tegra20. Before this change the throughput
+was capped to 30 Mbit/s on Tegra, now throughput is at 40 Mbit/s, which is
+a maximum throughput for the BCM4329 chip. The F2 block size is borrowed
+from the downstream BCMDHD driver. The comment in the BCMDHD driver says
+that 128B improves throughput and turns out that it works for the brcmfmac
+as well.
