Much of the point of using the linker is not to have to
care about where the variables ends up in memory.
Maybe it would help if you describe why you'd like
these to be in bank0 ?

If you want fast access, UDATA_SHR might be better.

Apart from that, you can create your own segments
in the LKR file to place UDATA blocks right where
yopu want.
