+Subject: [PATCH FIX] bgmac: fix device initialization on Northstar SoCs
+ (condition typo)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On Northstar (Broadcom's ARM architecture) we need to manually enable
+all cores. Code for that is already in place, but the condition for it
+was wrong.
+
+Signed-off-by: Rafał Miłecki <zajec5@gmail.com>
+---
+Can we have it for 3.20, please?
