It shouldn't be necessary to add them when there is no special
handling.  The device tree should list the earlier type they are
compatible with as well.  For example, every fsl,imx8*-usdhc I see in
a device tree then lists fsl,imx7d-usdhc additionally.

Though the Barebox driver does NOT list fsl,imx7d-usdhc.  It works on
the fsl,imx7d-usdhc because that is compatible with the

Really, the error would seem to be the NXP devicetrees only listing
imx7d as a compatible instead of going back to imx6sl.

It is also interesting that in Barebox, the imx7d uses the imx6sl
compat entry, and that entry includes ESDHC_FLAG_ERR004536.  While the
imx8* is supposedly imx7d compatible, it uses the imx6sx entry that
lacks that flag.  I think the error here is that imx7d does not have
this erratum.
