build/lattice/trellis: optionally allow failure if p&r timing not met
...
When timing requirements are strict, allow the build process to fail upon
failure to meet timing. This facilitates running the build process from a
loop, repeatedly, until a "lucky" p&r solution is found, e.g.:
while true; do
litex/boards/targets/versa_ecp5.py --gateware-toolchain trellis \
--sys-clk-freq=60e06 --cpu-type rocket --cpu-variant linux \
--with-ethernet --yosys-nowidelut \
--nextpnr-timingstrict
if [ "$?" == "0" ]; then
echo "Success" | mail -s "Build Succeeded" your@email.here
break
fi
done
This augments commit #683e0668, which unconditionally forced p&r to
succeed, regardless of whether timing was met, via '--timing-allow-fail'.

cpu/rocket: swap main_mem and io regions
...
The total size of RAM (main_mem) can be expected to vary significantly,
and often exceed the size needed for MMIO allocations by a large margin.
As such, place Rocket's MMIO (io regions) below 0x8000_0000, and start
the RAM (main_mem) at 0x8000_0000, with nothing above it to limit its
future growth.
Also, bump the pre-built Rocket verilog submodule to an updated version,
which also comes with matching changes to the way MMIO and RAM accesses
are mapped and routed to their respective AXI interfaces.

soc_core/cpu: add io_regions and deprecate shadow_base (with API retro-compat)
...
The shadow_base parameter has always been difficult to apprehend, replace it with
io_regions (uncached regions) defined user or the CPU.
The equivalent of a shadow_base parameter of 0x80000000 in the old API is:
io_regions = {0x80000000: 0x80000000} # origin, length
It's still possible to use shadow_base with retro-compat, but user is encouraged
to update and features will be removed in the future.
