This is intentional. U-Boot does not initialize all hardware on the
system, it initializes only such hardware which it needs for it's own
operation.
To initialize the RTC, the "date reset" command will be used; this
then includes the required init code.

This is bad. This code violates the U-Boot design principles and shall
be removed.
Mike, can you please take care to get rid of this code in the next
release? Thanks in advance.

No, definitely not.

No, please don't. I will reject any such patches.
