From 84d5dfbf09be6be71d6dda63d99a8303e85663c7 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Mon, 24 Sep 2012 07:54:33 +0200 Subject: 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.
