223  * ARM VMSAv8-64 defines an algorithm for finding the translation table
224  * descriptors in section D4.2.8 in ARM DDI 0487C.a.
225  *
226  * The algorithm defines the expectations on the translation table
227  * addresses for each level, based on PAGE_SIZE, entry level
228  * and the translation table size (T0SZ). The variable "x" in the
229  * algorithm determines the alignment of a table base address at a given
230  * level and thus determines the alignment of VTTBR:BADDR for stage2
231  * page table entry level.
232  * Since the number of bits resolved at the entry level could vary
233  * depending on the T0SZ, the value of "x" is defined based on a
234  * Magic constant for a given PAGE_SIZE and Entry Level. The
235  * intermediate levels must be always aligned to the PAGE_SIZE (i.e,
236  * x = PAGE_SHIFT).
237  *
238  * The value of "x" for entry level is calculated as :
239  *    x = Magic_N - T0SZ
240  *
241  * where Magic_N is an integer depending on the page size and the entry
242  * level of the page table as below:
243  *
244  *	--------------------------------------------
245  *	| Entry level		|  4K    16K   64K |
246  *	--------------------------------------------
247  *	| Level: 0 (4 levels)	| 28   |  -  |  -  |
248  *	--------------------------------------------
249  *	| Level: 1 (3 levels)	| 37   | 31  | 25  |
250  *	--------------------------------------------
251  *	| Level: 2 (2 levels)	| 46   | 42  | 38  |
252  *	--------------------------------------------
253  *	| Level: 3 (1 level)	| -    | 53  | 51  |
254  *	--------------------------------------------
255  *
256  * We have a magic formula for the Magic_N below:
257  *
258  *  Magic_N(PAGE_SIZE, Level) = 64 - ((PAGE_SHIFT - 3) * Number_of_levels)
259  *
260  * where Number_of_levels = (4 - Level). We are only interested in the
261  * value for Entry_Level for the stage2 page table.
262  *
263  * So, given that T0SZ = (64 - IPA_SHIFT), we can compute 'x' as follows:
264  *
265  *	x = (64 - ((PAGE_SHIFT - 3) * Number_of_levels)) - (64 - IPA_SHIFT)
266  *	  = IPA_SHIFT - ((PAGE_SHIFT - 3) * Number of levels)
267  *
268  * Here is one way to explain the Magic Formula:
269  *
270  *  x = log2(Size_of_Entry_Level_Table)
271  *
272  * Since, we can resolve (PAGE_SHIFT - 3) bits at each level, and another
273  * PAGE_SHIFT bits in the PTE, we have :
274  *
275  *  Bits_Entry_level = IPA_SHIFT - ((PAGE_SHIFT - 3) * (n - 1) + PAGE_SHIFT)
276  *		     = IPA_SHIFT - (PAGE_SHIFT - 3) * n - 3
277  *  where n = number of levels, and since each pointer is 8bytes, we have:
278  *
279  *  x = Bits_Entry_Level + 3
280  *    = IPA_SHIFT - (PAGE_SHIFT - 3) * n
281  *
282  * The only constraint here is that, we have to find the number of page table
283  * levels for a given IPA size (which we do, see stage2_pt_levels())
