From: Ang Tien Sung <tien.sung....@intel.com> commit ec82dae4b4a85d369d313a9628873ade5095bcf7 from https://github.com/altera-opensource/linux-socfpga.git
Increase the timeout for SDM (Secure device manager) data credits from 20ms to 40ms. Internal stress tests running at 500 loops failed with the current timeout of 20ms. At the start of a FPGA configuration, the CVP host driver reads the transmit credits from SDM. It then sends bitstream FPGA data to SDM based on the total credits. Each credit allows the CVP host driver to send 4kBytes of data. There are situations whereby, the SDM did not respond in time during testing.
