bool "Cadence QSPI driver"depends on DM_SPIhelpEnable the Cadence QSPI driver.Can we get a bit more detail here? What does QSPI mean? What features does it support?
Stefan ? ;-)
Its the IP core from Cadence supporting SPI NOR flash and is present on the Altera SoCFPGA. Enabling access to such SPI NOR flash devices. QSPI stands for Quad-SPI and refers to the optional use of up to 4 data lines for flash access.
So perhaps something like this:
