so would you take maintainer-ship?

Well, the base address is just used for the temporary copy of u-boot
inside RAM. After copy from media to RAM we will relocate to a runtime
defined address. This address depends on some variable parameters which
may also be defined at runtime. We had the problem that in some cases
the calculated relocation address collates with running u-boot in RAM.
The chance to hit this issue is high when you just have room of 1 MiB
(which must hold two copies of u-boot!)
Best regards
