Dan Callaghan be4c7cfb34 soc/cores/ram: allow populating initial values in Nexus LRAM
On designs which use Nexus parts without any external memory, it can be
difficult to fit an embedded ROM program larger than a few KiB. Radiant
cannot infer LRAM, and refuses to infer EBRAM under many circumstances
too, so large memories tend to just consume a huge number of LUTs.

This patch makes it possible to explicitly wire up an LRAM as a ROM,
populate its initial values with a program, and execute directly from
it. That lets us embed programs up to 64KiB.

Florent Kermarrec ad1fe143cc cores/uart: Cleanup code and add optional automatic TX Flush.
In some SoCs where UART's PHY is managed externally (ex through a Bridge) we don't
necessarily want the UART TX to wait for the PHY to be ready (and then stall the
CPU) but just want to let the CPU print the UART and will just connect when useful
and handle backpressure when connected.

This is now possible by calling add_auto_tx_flush method, ex in the SoC:
self.uart.add_auto_tx_flush(sys_clk_freq)

Florent Kermarrec b1d8fe61f8 cores/cpu: Add initial FemtoRV support.
FemtoRV is a minimalist RISC-V CPU with design process documented and
available at https://github.com/BrunoLevy/learn-fpga.

This CPU is a very nice way to discover/learn RISC-V and this LiteX support
can be useful to learn how to integrate a custom CPU with LiteX.

With this support, FemtoRV is now directly usable with LiteX Sim:
$litex_sim --cpu-type=femtorv

This should also enable its use on all boards (> 50) available in LiteX-Boards
repository (but hasn't been tested yet), ex:
$python3 -m litex_boards.targets.digilent_arty --cpu-type=femtorv --build
