DRIVER: PrimeCell UART (PL011) #5

For so long, I have been raw writing to 0x09000000. For so long, I have been accessing to memory in an unsafe way. For so long, I have keeping myself away from device drivers.

It ends "today" with the start of this issue!

The "driver/peripherals and I/O" journey begins with ARM's PrimeCell UART (PL011). I'll try to "fully" implement it. If it turns out to be too much time consuming, then I will just stick to basics. Not sure what awaits me but, what's the worst that could happen?

Godspeed 🐉
