* This is the offset of the uncached section from its cached alias.
*
* Legacy platforms handle trivial transitions between cached and
* uncached segments by making use of the 1:1 mapping relationship in
* 512MB lowmem, others via a special uncached mapping.
*
* Default value only valid in 29 bit mode, in 32bit mode this will be
* updated by the early PMB initialization code.
