Newer versions of Renode rename PrivilegeArchitecture to
PrivilegedArchitecture. They appear to have tried to work around this by
annotating it with `[NameAlias("privilegeArchitecture")]`, however that
doesn't change the fact that the actual type itself changed as well.
This incompatible change will cause breakage on older versions of
Renode.

The WF200 is connected via an 8-bit bus, but data is transferred in
chunks of 16-bits. That means that sometimes an extra byte is
transferred.
Suppress the warning that would occur when this happens to avoid
confusion.

Add "_zicsr_zifencei" to "rv32imac" when describing the CPU core. This
is required by newer versions of the spec, and will eventually be a
requirement of Renode.

The riscv foundation changed the descriptor of riscv cores. We must now
add "_zicsr_zifencei" to the "rv32i" designation in order to ensure we
have access to CSRs and the "FENCE.I" instruction.

For some reason renode is now complaining about a C# error where
a (ulong) cannot be cast to a (uint) type without an explicit
type cast.
This fixes that error. Seems to work ok.
Many of the devicse have changed from `uint` to `ulong`, so forward-port
the peripherals to work with the new format.

The ticktimer wasn't properly adjusting the upper bits, meaning delays
of more than 42 days did not function properly. This was discovered as
part of the libstd tests.

Precursor has a custom TIMER0 module that is different from other LiteX
timers. Adapt the Renode model to match the hardware.

When we started this project, all Renode Litex modules were 8-bits, and
we had to custom-make a 32-bit timer module. However, in the interim,
upstream has grown a 32-bit variant of this timer. As of this writing,
this change was made two years ago.
Remove our custom variant and use the upstream version instead.

Give a "Betrusted" namespace to all of the peripherals. This will enable
us to upstream various modules without breaking compatibility with our
own versions of these peripherals.

if anyone objects to these feel free to revert them, but it's
nice to have some helper scripts local to my machine in the root
dir that don't always show up in my status.
Use the `BackingFile` property of the SPI flash block in order to allow
SPI flash writes to persist across runs. This will write out the SPI
flash contents as data is written.

This audio codec lives on I2C and doesn't really do much for us.
However, by adding this device we can now pass `test oqc`.
The next step will be to implement `BetrustedI2S` which is where the
actual audio emulation occurs.
