5.2.3. L2 TLB

Misses from the L1 instruction and data TLBs are handled by a unified L2 TLB. This is a 512-entry 4-way set-associative structure. The L2 TLB supports all the VMSAv7 page sizes of 4K, 64K, 1MB and 16MB in addition to the LPAE page sizes of 2MB and 1GB.

Accesses to the L2 TLB take a variable number of cycles, based on the competing requests from each of the L1 TLBs, TLB maintenance operations in flight, and the different page size mappings in use.
