My fault (as expected); we did too much configuration in our bdi config:
by the time it booted, the ORn and BRn registers were set with the final
values, remapping flash and memory and not the default power on values.

Still work in progress, but the EDMS port works almost out of the box;
though the cs for DDR needed to be configurable in the config file
instead of 2/3; support for some spansion flash and BCSR in board
initialisation is only compiled when it is used/defined in the config
file.

Great work for the EDMS/ADS port.

Next hurdle:
TSEC0: PHY id ffffffff is not supported!
:)

What is the proper approach for a board variation: keep a single port
that is configured with different config/*.h files; possibly
adding/compiling more commands in the board directory based on the
define (e.g. flash support); or simply branching the port with quite
some code duplication that diverge? The first option might clutter the
*.c code with ifdefs while the second one keeps the code clearly/cleanly
seperate.

Ladies, some decorum please. This is a peace memorial, let's not kill
