| qspi testbench |
| ------------------------------------------------ |
| |
| This testbench is mainly a copy of the gpio testbench and uses the |
| same checks for pass/fail status. The difference is that the startup |
| C code puts the SPI flash into QSPI/DDR/CRM modes for fastest access |
| and enables the GPIO channels 36 and 37 to work as the flash IO2 and |
| IO3 channels. If the channel and spimemio setup works correctly, |
| then the testbench simulation will pass. |
