uart::KernelDriver UartDriver API

This pretends to be a hardware driver but is just a mock for tests. If

uart::mock::Sync is also used to instantiate uart::KernelDriver, then the

expected synchronization calls are primed into the Driver mock so their

ordering relative to the hardware driver calls can be tested. The mock

hardware Driver can also be used with other Sync API providers.

Driver & ExpectWrite (const std::basic_string_view<Char> chars)

Note this takes the chars that the Write call will consume, not the chars

it expects to be called with. The Write call might be passed more chars

and will consume (and verify) only this many.

void Init (IoProviderType & io)

uart::KernelDriver UartDriver API

Each method is a template parameterized by an an IoProvider type that

provides access to hwreg-compatible types accessing the hardware registers

via hwreg ReadFrom and WriteTo methods. Real Driver types can be used

with hwreg::mock::IoProvider in tests independent of actual hardware

access. The mock Driver to be used with hwreg::mock::IoProvider, but it

never makes any calls.

bool TxReady (IoProviderType & io)

Return true if Write can make forward progress right now.

template <typename It1, typename It2>

auto Write (IoProviderType & io, bool , It1 it, const It2 & end)

This is called only when TxReady() has just returned true. Advance

the iterator at least one and as many as is convenient but not past

end, outputting each character before advancing.
