111 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.

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

103 Removed the timescale from all RTL files.
Added possibility to exclude the "includes" statements from the RTL.

102 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+

34 To avoid potential conflicts with other Verilog modules in bigger projects, the openMSP430 sub-modules have all been renamed with the "omsp_" prefix. olivier.girard 5276d 14h /openmsp430/trunk/core/rtl/verilog/omsp_execution_unit.v
33 In order to avoid confusion, the following changes have been implemented to the Verilog code:
- renamed the "rom_*" ports and defines to "pmem_*" (program memory).
- renamed the "ram_*" ports and defines to "dmem_*" (data memory).

In addition, in order to prevent potential conflicts with the Verilog defines of other IPs, a Verilog undefine file has been created.
olivier.girard 5276d 15h /openmsp430/trunk/core/rtl/verilog/execution_unit.v
23 Renamed the "openMSP430.inc" file to "openMSP430_defines.v" & added the "timescale.v" file.
In order to follow the same structure as other OpenCores projects, the timescale and the defines are now included from within the Verilog files (using the `include construct).
