Thanks to Sebastien Van Cauwenberghe's contribution :-) |

Update hardware breakpoint unit with the followings:
- fixed hardware breakpoint bug with CALL instructions.
- modified data read watchpoint behavior to also trigger with read/modify/write instructions.
- removed unused ports. |

Re-organized the "openMSP430_defines.v" file.
Re-defined the CPU_ID register of the debug interface (in particular to support custom user versioning).
Added RTL configuration possibility to expand the peripheral address space from 512B (0x0000 to 0x0200) to up to 32kB (0x0000 to 0x8000).
As a consequence the per_addr bus width goes from 8 to 14 bits and the peripherals address decoders have been updated accordingly. |

Separated the Timer A defines from the openMSP430 ones.
Added the "dbg_en" port in order to allow a separate reset of the debug interface.
Added the "core_en" port (when cleared, the CPU will stop execution, the dbg_freeze signal will be set and the aclk & smclk will be stopped).
Renamed "per_wen" to "per_we" to prevent confusion with active low signals.
Removed to missing unused flops when the DBG_EN is not defined (thanks to Mihai contribution). |

Removed dummy memory read access for the MOV/PUSH/CALL/RETI instructions.
These were not problematic but this is simply cleaner that way. |

Fixed bug reported by Mihai ( http://opencores.org/bug,view,1955 ).
The following PUSH instructions are now working as expected:
- indexed mode: PUSH x(R1)
- indirect register mode: PUSH @R1
- indirect autoincrement: PUSH @R1+ |

This bug is CRITICAL for people using working with interrupts and the Serial Debug Interface. |

Cleanup of the PC (R0) generation logic.
Formal equivalence was shown between the new and old code with Synopsys' Formality (to make sure that nothing has been broken :-P ). |

Update design to exclude the range mode from the debug hardware breakpoint units. As this feature is not used by GDB, it has been disabled in order to improve the timings and save a bit of area/utilisation.
Note that if required, this feature can be re-enabled through the `HWBRK_RANGE define located in the "openMSP430_defines.v" file. |

Fixed the following combinatorial timing loop:
1- irq_detect (omsp_frontend)
2- decode (omsp_frontend)
3- dbg_swbrk (omsp_dbg)
4- halt_flag_set (omsp_dbg)
6- dbg_halt_cmd (omsp_dbg)
7- irq_detect (omsp_frontend)
Without this fix, problem could occur whenever an IRQ request arrives during a software breakpoint instruction fetch. |
