This implements the recommended workaround for this errata for chips
that use older versions of firmware that do not already handle it.
The last 4KiB of memory are hidden from the kernel to prevent the
problem transactions from occurring.

Do you know which versions of firmware have this problem?

Any U-Boot older than 1.3.3-rc1.  Not sure about PIBS, but I don't
think the version that is on my Bamboo board has a fix for it.

PIBS will definitely have this problem too. This errata is quite new on 
440EP/GR.
