(In reply to Gary Jennejohn from comment #10)
The driver from hlh is much further along than mine.  Loading the module with a
SD card plugged in actually results in MMC seeing the card and reading its
capacity.  Plugging in a card after the module is loaded results in a spurious
interrupt error, but that can probably be fixed without much trouble.

I had to add ``#include <sys/mutex.h>'' to get it to compile in my FreeBSD13
tree.

It doesn't work too well with my 522A and I see timeouts waiting for interrupts
quite often.

In any case, my opinion is that this driver is the way forward and hlh should
continue working on it.
