What would be the purpose of this in a boot loader?

For Linux iot makes sense to free each and every  byte  which  is  no
longer  needed  because  applications running can really benefir from
it. But in U-Boot? Please check the memory map of the running system.
The memory regained will not even be usable by anybody...

What sort of benefit do you expect?

Best regards,

Wolfgang Denk
