At the moment, if bdi is not plugged in, board does not boot (see no activity on serial console).
I will read reset section of MPC8xx User's Manual and thanks for the tip, will relocate flash.

This is definitely not a good memory map, especially not in case you want to use it on Linux later.
Well, in order to start executing u-boot code from flash without
bdi
attached, what needs to be done and where.
Detach BDI?
I have some confusion in my mind. I know that higher order bits
will
be ignored (by settings of br0 & or0 registers). Even in this case changes should be made in u-boot or someplace else. If this is
u-boot,
What sort of changes should be made? Who says so?
than its kind of checken and egg problem. How will it know before reading u-boot settings for br0 & or0.
Read the MPC8xx User's Manual section about how reset works.
