The building process generates 3 Linux modules:

*kernel/fmc-adc-100m14b4ch-svec.ko*.
Top Level Driver
================
The fmcadc100m14b4ch is a generic driver for an FPGA device that could
be instanciated on a number of FMC carriers. For each carrier we write
a little Linux module which acts as a top level driver (like the MFD
drivers in the Linux kernel). In these modules there is the knowledge
about the virtual memory range, the IRQ lines, and the DMA engine to
be used.
The top level driver is a platform driver that matches a string
containing the application identifier. The carrier driver builds this
identification string from the device ID embedded into the FPGA
(https://ohwr.org/project/fpga-dev-id).
