integration/soc: Add initial AXI-full support.
...
Main bus can now be switched to AXI-full with --bus-standard=axi.
The interconnect will be AXI-Full (Using Alex Forenchich's verilog_axi
Interconnect and Crossbar) but ROM/SRAM will still be in AXI-Lite (Will
be switched to AXI-full in the future).
This gives a first working version that can be used for further improvements.
Note that the interconnect can also be selected by --bus-interconnect=shared or
crossbar.

soc/cores/cpu: add initial OpenC906 support
...
It's only boot tested in sim and build tested in Vivado now, and it
requires a FPGA > 100k LUT4 (XC7A100T currently does not fit).
The ISR code is based on Rocket one.
These Python code depends on a forked version of OpenC906 at [1].

Reuse of external defined CSR_BASE has been added for some use-cases, allowing more

cpu/vexriscv: Redo csr instruction fix
...
Instead of enabling the zicsr extension in crt0.S, change -march to
specify that VexRISCV implements version 2.0 of I, rather than the
latest (2.1). In 2.0 the csr instructions were still part of I.
This approach has two advantages:
* It is compatible with older versions of binutils, since they do not
need to know about the new zicsr extension
* By modifying the -march in CFLAGS, csr instructions can be used in any
code (for example by the inline functions in irq.h), not just in crt0.S.
