+Subject: [PATCH 114/203] firmware: bcm2835: Support ARCH_BCM270x
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Support booting without Device Tree.
+Turn on USB power.
+Load driver early because of lacking support for deferred probing
+in many drivers.
