This PR adds Pancake drivers for the serial device class for most platforms except virtio, and the corresponding serial queue implementation. It does not include the virtualisers for the serial subsystem, which will be upstreamed later.
This is based on Richard Shen's work during his thesis. I added some new drivers and also updated the code to make it consistent with the C implementation.
In general, the current Pancake implementation still requires the corresponding C code for initialisation. In the Makefile, a new variable
PANCAKE_SERIAL_DRIVERis introduced to select the Pancake implementation during compile time, which is off by default for now.The
inlinekeyword of Pancake may not be supported by older compilers. We should decide how to handle compatibility issues like this.
