I am planning on reading ADC data periodically from and FPGA over the QSPI interface. I want to be able to have read/write access to the FPGA (via QSPI interface) as if the FPGA was just a memory mapped device.
Is this possible? I know that the Linux driver provides high level access to allow reading and writing files over QSPI. However, what I want to know is whether I can have lower level access to the QSPI to make the FPGA look like an attached memory device. Will I need to write my own QPSI device driver or can I simply tweak the existing driver?
