-The old logic assumes CMDLINE_FROM_BOOTLOADER vs. CMDLINE_FORCE and
-ignores CMDLINE_EXTEND.  Here's the old logic:
-
-- CONFIG_CMDLINE_FORCE=true
-    CONFIG_CMDLINE
-- dt bootargs=non-empty:
-    dt bootargs
-- dt bootargs=empty, @data is non-empty string
-    @data is left unchanged
-- dt bootargs=empty, @data is empty string
-    CONFIG_CMDLINE (or "" if that's not defined)
-
-The new logic is now documented in of_fdt.h and is copied here for
-reference:
-
-- CONFIG_CMDLINE_FORCE=true
-    CONFIG_CMDLINE
-- CONFIG_CMDLINE_EXTEND=true, @data is non-empty string
-    @data + dt bootargs (even if dt bootargs are empty)
-- CONFIG_CMDLINE_EXTEND=true, @data is empty string
-    CONFIG_CMDLINE + dt bootargs (even if dt bootargs are empty)
-- CMDLINE_FROM_BOOTLOADER=true, dt bootargs=non-empty:
-    dt bootargs
-- CMDLINE_FROM_BOOTLOADER=true, dt bootargs=empty, @data is non-empty string
-    @data is left unchanged
-- CMDLINE_FROM_BOOTLOADER=true, dt bootargs=empty, @data is empty string
-    CONFIG_CMDLINE (or "" if that's not defined)
