Could you boot with earlycon enabled to at least have a clue of what's happening ?

BPI-M2S (A311D) is booting fine on v6.15-rc, see https://gitlab.com/amlogic-foss/abcd-linux-test/-/jobs/10004997032

But perhaps something specific to the VIM3 is breaking, do you change the kernel config for the DRM ?
