The Pi image is forked from here https://github.com/pyavitz/rpi-img-builder It is based on the official Raspberry Pi kernel https://github.com/raspberrypi/linux (rpi-6.1-y branch ) with Debian Bookworm wrapped around it. It uses a cross compilation environment so it gets built on x86 hardware. It has a good scripting environment that allows us to install linuxcnc as part of the build process.. The download page desperately needs a paragraph outlining the username (cnc) and password (cnc) and the need to run sudo menu-config to complete the build. I have no idea where the source is for that page or I would do a PR. Builds for both the pi4b/400 and the pi5 are supported by setting the board parameter at build time. The Pi4 version supports the gpiod driver which is documented. https://linuxcnc.org/docs/stable/html/drivers/hal_gpio.html Preempt_rt patches are supported but the challenge here is always to match the kernel being built with the patched RT version. We can specify the commit to pull so we can match to the RT patch but currently, the latest kernels that have been patched have not been merged into the pi source.
As far as spi and gpio on the pi5 go, that board was never in scope. It is up to the devs to devise appropriate drivers as its out of scope of the installer.
