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)

Fix gcc warnings: use 'unsigned long' to represent memory addresses,
and remove 'static' from the definition of 'cdelay()', as it is called
from multiple C files.

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

Florent Kermarrec d0e8de077c soc/SoCController: Add separate fields for SoC and CPU resets.
As discussed in #909, in some specific cases, it can be interesting to be able
to keep the CPU in reset while the rest of the SoC is still operating (ex the
peripherals/bridges).

With theses changes, the old behaviour is preserved to do a full SoC Reset (at
the exception that writing a 1 is now mandatory) and a separate field specific
to the CPU reset is added.

The SoC Reset is a pulse (otherwise the system would be stuck in Reset) while
the CPU Reset is based on the register value (so can be pulse or hold).
