-Subject: [PATCH 1/6] MIPS: BCM47xx: Really fix 128MB RAM problem
-
-The previews patch 84a6fcb368a080620d12fc4d79e07902dbee7335 was wrong,
-I got wrong success reports.
-
-The bcm47xx architecture maps the ram into a 128MB address space. It
-will be paced there as often as goes into the 128MB. The detection
-tries to find the position where the same memory is found. When reading
-over 128MB the processor will throw an exception. If 128MB ram is
-installed, it will not find the same memory because it tries to read
-over the 128MB boarder. Now it just assumes 128MB installed ram if it
-can not find that the ram is repeating.
