+       help
+         While we expect to call a pointer to a valid FDT (or NULL)
+         as the platform parameter to an ATF, some ATF versions are
+         not U-Boot aware and have an insufficiently robust parameter
+         validation to gracefully reject a FDT being passed.
+
+         If this option is enabled, the spl_atf os-type handler will
+         always pass NULL for the platform parameter.
+
+         If your ATF is affected, say Y.
