With CFG_CORE_PREALLOC_EL0_TBLS=y translation tables are allocated for a
user space context at the time when the mapping is added a struct
vm_region. The translation tables will be kept available for the S-EL0
context as long at the mappings are unchanged.
Secure Partitions (SPs) can depend on translation tables always being
available and avoid having to wait for translation tables.
Memory for the translation tables is allocated from the same memory as
used for TAs and SPs. The number of available translation tables are
limited by the amount of TA/SP memory available.
