8 * This is the offset of the uncached section from its cached alias.
10 * Legacy platforms handle trivial transitions between cached and
11 * uncached segments by making use of the 1:1 mapping relationship in
12 * 512MB lowmem, others via a special uncached mapping.
14 * Default value only valid in 29 bit mode, in 32bit mode this will be
15 * updated by the early PMB initialization code.
