+Subject: [PATCH] tty: serial: bcm63xx: use more precise Kconfig symbol
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Patches lowering SERIAL_BCM63XX dependencies led to a discussion and
+documentation change regarding "depends" usage. Adjust Kconfig entry to
+match current guidelines. Make this symbol available for relevant
+architectures only.
