It seems to me that your patch does much more as what you describe in
the commit message.

Make a note in the commit message about these changes (not related to
the subject)

However, these change fix another issue. You want to cleanup
u-boot-spl.lds, but then there are some other parts I cannot understand.
For example, why is __u_boot_cmd_start = needed ?

If your goal is to cleanup the linker file, please submit a separate
patch removing also the unused sections in SPL.

Best regards,
Stefano Babic
