This helps to reduce the driver model overhead. +It is possible to limit this to specific relocation steps, by using +the more specialized 'u-boot,dm-spl' and 'u-boot,dm-tpl' flags +in the devicetree. + Then post relocation we throw that away and re-init driver model again. For drivers which require some sort of continuity between pre- and post-relocation devices, we can provide access to the pre-relocation
