For some FPGAs (e.g. MAX10) .rbf file cannot be generated.
Add possibility to turn off that feature for those chips.

software/libbase: memcpy: simple, arch-width agnostic implementation
...
Remove optimizations targeted specifically at rv32 architecture,
allowing memcpy to work on all word sizes.
Since this is "only" the BIOS, it is also arguably better to
optimize for size rather than performance, given that control
will be quickly handed over to some other program being loaded.

fixup: generated-verilog submodule for experimental Rocket support

FIXME: This patch uses https://github.com/gsomlo/rocket-litex-verilog ,
however in the long term it would perhaps be better if enjoy-digital
hosted the generated-verilog repository.
Once that's in place, I'd be happy to re-spin (and squash) this patch
on top of its parent -- GLS

soc/cores/cpu/rocket: Support for 64-bit RocketChip (experimental)

Simulate a Rocket-based 64-bit LiteX SoC with the following command:
litex/tools/litex_sim.py [--with-sdram] --cpu-type=rocket
NOTE: Synthesizes to FPGA and passes timing at 50MHz on nexys4ddr
(with vivado) and ecp5versa (with yosys/trellis/nextpnr), but at
this time does not yet properly initialize physical on-board DRAM.
On ecp5versa, using '--with-ethernet', up to 97% of the available
TRELLIS_SLICE capacity is utilized.

When we get an error with errno 13, it means that the user doesn't

error and returning -1, print out a message to aid in debugging.

The previous value -- 0xc0 -- is used by Windows all the time to query
special descriptors. This was causing a conflict when using the USB
bridge on a Windows device.
Change the magic packet from "Vendor: Device" queries to "Vendor:
Other" by setting the bottom two bits.
