f6297437c0 linux.py: Allow specifying a separate TTY device 
This allows e.g. opening a TTY on the UART serial device after
booting the kernel via USB.

7dfe24ee2c Rework kboot/chainload flow to shut down before calling the next stage 
Next stage boots now exit back to main() after replying to the proxy
command, allowing shutdown functions to be called. Introduces a new
P_VECTOR proxy op, distinct from P_CALL. The Python side is reworked
to remain compatible with older versions that do not support this.

d63e84d2f7 fb: add fb_console_reserve_lines() 
This is like fb_console_scroll(), but only scrolls if necessary to
ensure that enough free space is available at the end of the console.
This avoids spuriously scrolling during shutdown if we still have space.
