svn commit: r297426 - in head/sys: arm/conf boot/fdt/dts/arm

[Emmanuel Vadot]

 Hi Luiz,

 Why setting the pins to SPI mode here ? This should be done in your own board dts file if you need it (unless there is some spi chip on the BBB that I don't know of). 
 This reduce the number of GPIOs available on the headers.

 Thanks,
