/**
* GENERAL DESCRIPTION:
*
* This module initializes and provides for other SW modules the access to the
* FPGA OSC module. The oscilloscope memory space is divided to three parts:
* - registers (control and status)
* - input signal buffer (Channel A)
* - input signal buffer (Channel B)
*
* This module maps physical address of the oscilloscope core to the logical
* address, which can be used in the GNU/Linux user-space. To achieve this,
* OSC_FPGA_BASE_ADDR from CPU memory space is translated automatically to
* logical address with the function mmap(). After all the initialization is done,
* other modules can use this module to controll oscilloscope FPGA core. Before
* any functions or functionality from this module can be used it needs to be
* initialized with osc_fpga_init() function. When this module is no longer
* needed osc_fpga_exit() must be called.
*
* FPGA oscilloscope state machine in various modes. Basic principle is that
* SW sets the machine, 'arm' the writting machine (FPGA writes from ADC to
* input buffer memory) and then set the triggers. FPGA machine is continue
* writting to the buffers until the trigger is detected plus the amount set
* in trigger delay register. For more detauled description see the FPGA OSC
* registers description.
*
* Nice example how to use this module can be seen in worker.c module.
