From ecc240f90bce23651f9866a1523ba55faa89f009 Mon Sep 17 00:00:00 2001 From: Geoff Levand Date: Fri, 16 May 2008 06:09:59 +1000 Subject: [PATCH] [POWERPC] PS3: Fix memory hotplug A change was made to walk_memory_resource() in commit 4b119e21d0c66c22e8ca03df05d9de623d0eb50f that added a check of find_lmb(). Add the coresponding lmb_add() call to ps3_mm_add_memory() so that that check will succeed. This fixes the condition where the PS3 boots up with only the 128 MiB of boot memory, and doesn't see the other 128MiB that is available.
