203 *
204 * To help platforms who may need to differenciate MMIO addresses in
205 * their hooks, a bitfield is reserved for use by the platform near the
206 * top of MMIO addresses (not PIO, those have to cope the hard way).
207 *
208 * This bit field is 12 bits and is at the top of the IO virtual
209 * addresses PCI_IO_INDIRECT_TOKEN_MASK.
210 *
211 * The kernel virtual space is thus:
212 *
213 * 0xD000000000000000 : vmalloc
214 * 0xD000080000000000 : PCI PHB IO space

216 * 0xD0000fffffffffff : end of ioremap region
217 *
218 * Since the top 4 bits are reserved as the region ID, we use thus
219 * the next 12 bits and keep 4 bits available for the future if the
220 * virtual address space is ever to be extended.
221 *
222 * The direct IO mapping operations will then mask off those bits
223 * before doing the actual access, though that only happen when
224 * CONFIG_PPC_INDIRECT_IO is set, thus be careful when you use that
225 * mechanism
