This can be flashed to e.g. the duet wifi using bossac. It requires a
later version as is currently included in the klipper repo (1.8
vs. 1.2). Comms are currently via UART0 only, USB serial is still TBD

Compile the PRU binary with -Os optimization, but request that the
timer dispatch code be compiled with -O2 optimization. This improves
the performance of timers slightly.

The gcc -Os option significantly reduces the size of the PRU binary
and it has little impact on performance.

The term "firmware" is ambiguous - it could refer to the entire
project (host and micro-controller software) or to just the
micro-controller software. Avoid the term in the documentation.

The Klipper software has progressed to the point where it does not
need to be described as "experimental" software.

Some additional tweeks to the scheduler has resulted in minor
improvements to the stepper benchmarks.

Change the default compression error window (max_error) from 50us to
25us - it's common for stepper motor drivers to have 30us for their
"pwm fixed off time" and it would be good for the steps to be
scheduled within that time.
