interconnect/csr_bus/SRAM: add mem_size check
...
Memory size is limited to 512 bytes:
- CSR region size is 0x800 (4096)
- default csr_data_width is 8
maximum size = 4096/8 = 512 bytes.

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'.
