+Subject: [PATCH] MIPS: BCM47xx: Read board info for all bcma buses
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Extra bcma buses may be totally different models, see following dump:
+boardtype=0x0646
+pci/1/1/boardtype=0x0545
+pci/2/1/boardtype=0x62b
+We need to detect them properly to allow drivers apply some board
+specific hacks.
+
+[ralf@linux-mips.org: folded in Rafal's fix.]
