Err, the interrupt handler intr_handler() calls the ->get_error_info()
function pointer and then calls handle_error(). I.e, the same path
ending in handle_error() is called on both: Zynq and ZynqMP, one through
the interrupt and the other through the poller.

Because it looks like the interrupt support is only on ZynqMP? I'm
looking at that DDR_ECC_INTR_SUPPORT thing.

If so, then you need to rename the interrupt handler to

And normal Zynq platform uses check_errors() which then calls

So still not good enough: you probably "fixed" it on ZynqMP but broke
it on Zynq because check_errors() calls ->get_error_info() which is
zynq_get_error_info() and will have populated pinf->col.

You need to differentiate between Zynq and ZynqMP in handle_error() and
issue the proper string depending on the platform.
