tools: remove vexriscv_debug
...
This program is no longer needed.
The `openocd_vexriscv` package natively supports `etherbone`, and now
that the vexriscv debug module is available on Wishbone instead of as a
CSR, this module no longer works.
This change simplifies both tooling (because there is one fewer program
to run) and integration (because you don't need to modify your CSRs
anymore, just `register_mem()`.)

vexriscv: reset wishbone bus on CPU reset
...
If the CPU is resetting during a Wishbone transfer, assert the ERR line.
Because the resetOut line is likely multiple cycles long, this should
give Wishbone enough time to finish its transfer, which will cause d.stb
and i.stb to go to 0, which will return d_err and i_err to 0.

vexriscv: put debug bus directly on wishbone bus
...
By placing the VexRiscv debug bus on the Wishbone bus, the Etherbone
core can access 32-bit values directly from the core. Additionally,
both reading and writing are supported without the need to do a SYNC
register as before.
Additionally, the address of the Wishbone bus won't move around anymore,
as it's fixed when doing `self.register_mem()`.

vexriscv_debug: use csr read()/write() accessors
...
CSR access widths can be different from register widths. 8-bit
registers are common.
The runtime-generated `read()` and `write()` functions handle this
mapping correctly. When direct register accesses are handled, this
mapping is lost.
Use the accessor functions rather than directly accessing the memory
addresses, so that we work on platforms other than 32-bit-wide.

vexriscv: debug: fix reading DATA register
...
The REFRESH register accepts an 8-bit address and determines which
register to refresh. Since there are only two addresses currently in
use, this register can be either 0x00 or 0x04.
A refactor replaced the compare with one that checked for any 0 bits.
Since both 0x00 and 0x04 have 0 bits, this check always evaluated as
true, causing the logic to always refresh the CORE register.
Replace this check with an explicit check for 0x00.

Add support for debugging the CPU, and gate it behind a new cpu_debug
parameter. With this enabled, a simple Wishbone interface is provided.
The debug version of the core adds two 32-bit registers to the CPU.
The register at address 0 indicates status, and is used to halt
and reset the core.
The debug register at address 4 is used to inject opcodes into the
core, and read back the result.
A patched version of OpenOCD can be used to attach to this bus via
the Litex Ethernet or UART bridges.

become extended in the future with full AXI support and more structures
(Wishbone bridge, interconnect, ...). For now this will do.
The bridge has been simulated (and includes an FHDL testbench) and
tested in hardware (on a Zynq 7020).

Specify top-level module in Lattice Diemond build script.

When building multi-source files the toolchain gets confused as to which
module is top-level. This ensures that the build_name of the design is

When building a design with PicoRV32 we end up with multiple top-level
modules and Verilator becomes confused as to which is the right one.
This change ensures the dut.v generated by the sim build process has
it's top-level name set to 'dut' and that verilator is invoked with this
name.

Implement IRQ software support for RISC-V.
...
Well, at least PicoRV32-specific. Turns out there is no RISC-V
specification for simple microcontroller-like interrupts, so PicoRV32
implements its' own based on custom opcodes.
It's somewhat esoteric, and for example doesn't offer a global interrupt
enable/disable. For this we implement a thin wrapper in assembly and
then expose it via a few helpers in irq.h.

cpu: Adding "variant" support.
...
It is useful to support slightly different variants of the CPU
configurations. This adds a "cpu_variant" option.
For the mor1k we now have the default mor1k configuration and the
"linux" variant which enables the features needed for Linux support on
the mor1k.
Currently there are no variants for the lm32, but we will likely add a
"tiny" variant for usage on the iCE40.

Wait longer before giving up on the 2nd tftp block.
...
Previously we would wait the same number of iterations as it took us to
receive the first data block after sending the request. When using the
build in tftp server in qemu, the first wait loop succeeds (and thus
breaks when 'i' is still 0.
Since the counter was never reset between the first and second data
block, under qemu the tftp_get call would fail before ever checking if
we have received the second block of data.
Now that we initialise 'i' to 12M, we ensure that we wait the same
amount of time for the second data block as it previously did for the
third (and subsequent) blocks.

vivado: Fix segfault with or1k.
...
The or1k doesn't have any verilog include paths added. This means the
code use to generate;
```tcl

```
which causes Vivado to segfault with the following error;
```
Command: synth_design -top top -part xc7a50t-csg325-2 -include_dirs {}

gen/sim, fhdl: remove port.we_granularity limitation on simulations
...
We have to find a way to eliminate all replaced memory ports from specials,
here we use a workaround and remove remaining _MemPorts before simulating.
If possible, proper way would be to remove replaced ports from specials.
Another solution can to remove all ports that are no longer associated with
a Memory.
