+Subject: [PATCH] ARM: BCM5301X: Add DT entry for SPI controller and NOR flash
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Controller is present on every BCM4708* board but only few devices have
+serial flash attached so mark it as disabled by default.
