From 7177efc5b030012c54c2e217c9d6decc0bcc1c53 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Tue, 28 Oct 2014 13:30:23 +0100 Subject: [PATCH 156/158] MIPS: BCM47XX: Make bcma init NVRAM instead of bcm47xx polling it MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This drops ssb/bcma dependency and will allow us to make it a standalone driver.
