** Description changed: + [Impact] + + Noble raspi 6.8 doesn't support Pi CM5 lite (and Pi 500) due to missing + DTBs. + + [Fix] + + Add missing DTB and align with upstream raspberrypi. + + [Test Case] + + Install updated kernel and verify CM5 lite boots. + + [Where Problems Could Occur] + + This adds new devicetree files so should not introduce any regressions. + However, due to the nature of the patches, there are slight + modifications to base bcm2712 DTBs so any Pi 5 could be affected. + + [Original Description] + Looks like the final missing puzzle piece for CM5 support on noble is a couple of missing dtbs in the linux-raspi package for the CM5 lite specifically: bcm2712-rpi-cm5l-cm5io.dtb and bcm2712-rpi-cm5l-cm4io.dtb. Without these present, the CM5 lite variant won't boot. Appears the kernel itself is largely fine: I copied these dtbs from our oracular image back to noble, booted the result on CM5 lite and things worked nicely (with the patched flash-kernel from LP: #2097008). Ideally, it would be great to get these added before noble's .3 release later this year to ensure that point release can fully support the CM5 family.
