-/**
- * GENERAL DESCRIPTION:
- *
- * AXI slave used also for simple bus master.
- *
- *
- *                     /------\
- *   WR ADDRESS  ----> |  WR  |
- *   WR DATA     ----> |      | -----------
- *   WR RESPONSE <---- |  CH  |            |
- *                     \------/       /--------\
- *                                    | SIMPLE | ---> WR/RD ADDRRESS
- *   AXI                              |        | ---> WR DATA
- *                                    |   RP   | <--- RD DATA
- *                                    |  BUS   | <--- ACKNOWLEDGE
- *                     /------\       \--------/
- *   RD ADDRESS  ----> |  RD  |            |
- *   RD DATA     <---- |  CH  | -----------
- *                     \------/
- *
- *
- * Because AXI bus is quite complex simplier bus was created.
- *
- * It combines write and read channel, where write has bigger priority. Command
- * is then send forward to red pitaya bus. When wite or read acknowledge is
- * received AXI response is created and new AXI is accepted.
- *
- * To prevent AXI lockups because no response is received, this slave creates its
- * own after 32 cycles (ack_cnt).
