    @ Banner stub for SBL1 logger call at 0x802f690 (patched to bl here).
    @ r0 = string. Print raw bytes via UARTDM until NUL (cap 256).
-    @ Preserve lr (set by bl) and return to caller with r0=0.
+    @ The original callee is noreturn (b.n self follows the call), so
+    @ jump on to 0x802f694 (post-banner init) instead of returning.
