instructions. It differs in many ways with memory access, and it's much
slower. It's unset by default, but some arch exposing legacy UART ports
might need it.

This introduces a generic driver set for console messages routed over
inter-processor interrupt (IPI) channels. These drivers bind to a
low-level IPI driver instance for the actual transport of messages.
ipi_console_sender installs printk and/or stdout hooks to forward
messages over IPI. There is currently no buffering on the sending side.
ipi_console_receiver installs an IPI callback which stashes incoming
characters into a ring buffer, which is monitored by a nanokernel
fiber. The fiber buffers the characters on a per-line basis and sends
them to either printk or stdout. Multiple instances of this driver
may be created in case you need to receive console data from multiple
CPUs.

up to the controller to request via an interrupt to get its fifo
filled-in. (TFS bit on SSSR register is the one requesting such
filling)
- Disabling the controller once completed (following transfer will
re-enable it)
