This isn't intended to make any overt behavioral change, but
there is a slight one in the value of CP_VERSION that will be used
during CI, because it will now include `--always --match "..."`,
so there could be a change to the uploaded name of the mpy-cross
artifacts on s3.
This targets the 64-bit CPU Raspberry Pis. The BCM2711 on the Pi 4
and the BCM2837 on the Pi 3 and Zero 2W. There are 64-bit fixes
outside of the ports directory for it.
There are a couple other cleanups that were incidental:
* Use const mcu_pin_obj_t instead of omitting the const. The structs
themselves are const because they are in ROM.
* Use PTR <-> OBJ conversions in more places. They were found when
mp_obj_t was set to an integer type rather than pointer.
* Optimize submodule checkout because the Pi submodules are heavy
and unnecessary for the vast majority of builds.
Fixes#4314
This configuration is used by @ladyada and more often than it should
we've discovered late that a change introduced problems building
there.
By adding this to regular CI, hopefully we learn about and fix these
issues sooner rather than later.
