+Subject: [PATCH] mmc: bcm2835: Add new driver for the sdhost controller.
+
+The 2835 has two SD controllers: The Arasan sdhci controller (supported
+by the iproc driver) and a custom sdhost controller.  This patch adds a
+driver for the latter.
+
+The sdhci controller supports both sdcard and sdio.  The sdhost
+controller supports the sdcard only, but has better performance.  Also
+note that the rpi3 has sdio wifi, so driving the sdcard with the sdhost
+controller allows to use the sdhci controller for wifi support.
+
+The configuration is done by devicetree via pin muxing.  Both SD
+controller are available on the same pins (2 pin groups = pin 22 to 27 +
+pin 48 to 53).  So it's possible to use both SD controllers at the same
+time with different pin groups.
+
+The code was originally written by Phil Elwell in the downstream
+Rasbperry Pi tree.   In preparation for the upstream merge it was
+cleaned up and the code base was moderized by Eric Anholt, Stefan
+Wahren and Gerd Hoffmann.

Could the lower maximum txpower be the result of not running with the 
proprietary driver ?

What would the source file with the merged support be named, mach-all0258n.c, 
mach-enh20x.c, or … ?

A few more questions:
Apart from this file and putting the dev’s make stances in generic.mk, which of 
the other files that were patched with the v1 patch should be handled 
differently ?
When changing the make stances, what is a good way to rebuild the config 
without going through make clean (my build laptop sports just 3 GB and an Intel 
C2D, so a complete build does take quite some time) ?
