How about DM_F_STRICT_BOOTPH ? or DM_F_CHILD_BOOTPH ?
Yes, this should be more descriptive, will include this in v2.
It indicates that it relates to driver model before relocation.
This behaviour is actually required by the schema. I agree it should
be optional, but only due to its performance issues.
A Binman solution would not have any performance issues.
Will explore on this more, if you have some more pointers on this,
then do let me know.
