Why would you need to initialize DDR though the JTAG debugger?

The common use of a JTAG debugger to debug U-Boot is _not_ to
initialize the system at all though JTAG, as this will be done by
U-Boot.  Just start the CPU out of reset.

Actually on quite a number of architectures U-Boot expects to find a
virgin CPU right out of reset, and any previous meddling with the
configuration may have unexpected (and usually adverse) effects.
Better don't do it.

Best regards,

Wolfgang Denk
