Add it as to the list of combinations in https://github.com/raspberrypi/linux/blob/rpi-6.6.y/.github/workflows/kernel-build.yml#L23-L56 and CI would build it for you.

This looks OK, but we'll need to be careful that the new file is created to match the latest arm64/bcm2711_defconfig - this version is already missing three options:

< CONFIG_GPIO_FXL6408=m
< CONFIG_DRM_PANEL_ILITEK_ILI9806E_SPI=m
< CONFIG_SND_PISOUND_MICRO=m

Yes, before this is merged we need to make sure it's in sync and stays in sync. Just using it to run a few normal / RT benchmarks and check for anything weird right now.
