With newer bootloader versions the crd-r3 (aka CRD 1.0 and 2.0) is

Add the compatible strings 'google,piglin-rev{3,4}'. The hoglin entries
are kept to make sure the board keeps booting with older bootloader
versions.
The older bootloaders really look for the google,hoglin-rev3/google,hoglin-rev4
compatibles or just google,hoglin? If its just google,hoglin, won;t it pick the
crd-rev5+ dtb now?
The compatible string 'google,piglin' (without revision information) is
still used by the IDP2 board, which is not expected to evolve further.
