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()`.)

6 years agovexriscv: reset wishbone bus on CPU reset

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()`.
