My build scripts already apply that patch when
they build U-Boot.

Hiren's problem is the FreeBSD kernel failing to mountroot.
The kernel should be doing its own probe and configuration
of the SD card.

I saw a similar problem a little while back here and
noticed it failed exactly when the kernel probed it at
50MHz.  When the kernel probed at 25MHz all was
good.
