[meta-xilinx] system.bit from digilent

[Mike Looijmans]

I think you're just missing a #include in the code. In the older kernel, that 
missing include just came along with another header. Probably that header has 
been fixed in mainline, removing the unneeded extra include that your C file 
needs.
