Subject: [Buildroot] SPI module on Raspberry Pi B+

Hello,

I just switched from Buildroot 2015.08.1 to 2015.11.1, and tried to keep 
the same configuration. SPI was working well, before the switch.

Now, I am having some trouble with the SPI driver, namely spi_bcm2835 : 
when I insert the module, there is no log in dmesg output, and nothing 
is created in /sys/bus/spi/devices.

I could make it work by loading spi_bcm2708 instead, despite the 
deprecated warning. In this case, I get some logging messages and 
/sys/bus/spi/devices/spi0.0 and /sys/bus/spi/devices/spi0.1 appear.

Any idea ?

David.
