From 4287441c0f9aa682b4c7f6f9021062cc7e93196f Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Mon, 24 Sep 2012 07:54:33 +0200 Subject: [PATCH] ARM: Orion5x: Fix too small coherent pool. Some Orion5x devices allocate their coherent buffers from atomic context. Increase size of atomic coherent pool to make sure such the allocations won't fail during boot.
