The TLB supports the TLB lock-by-entry model as described in the ARM Architecture Reference Manual. CP15 preload TLB instructions support loading entries into the TLB to be locked. Any preload operation first looks in the TLB to determine if the entry hits within the TLB array. If the entry misses, a hardware translation table walk loads that entry into the TLB array. See c10, TLB Lockdown Registers and c10, TLB preload operation for more information.
