└─>Tango SMP8759 PCIe controller (DANGEROUS)
In linux kernel since version 3.10 (release Date: 2013-06-30)  
Say Y here to enable PCIe controller support for Sigma Designs
Tango SMP8759-based systems.

Note: The SMP8759 controller multiplexes PCI config and MMIO
accesses, and Linux doesn't provide a way to serialize them.
This can lead to data corruption if drivers perform concurrent
config and MMIO accesses.
