From 4601ae5d9042580a47ab6f94f9182d51a2f91674 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Sun, 4 Dec 2011 13:13:58 +0000 Subject: [PATCH] powerpc/pseries: Increase minimum RMO size from 64MB to 256MB The minimum RMO size field in ibm,client-architecture is currently ignored, but a future firmware version will rectify that. Since we always get at least 128MB of RMO right now, asking for 64MB is likely to result in boot failures. We should bump it to at least 128MB, but considering all the boot issues we have on 128MB RMO boxes and all new machines have virtual RMO, we may as well set our minimum to 256MB.
