+# The coredump backend and memory-dump amount are Kconfig 'choice' symbols
+# with an in-tree default. As noted above, this defconfig is sourced after the
+# Zephyr tree, so choice defaults cannot be overridden from here; the ADSP
+# memory-window backend and minimal dump are therefore selected in each Intel
