      Automatically select initial xlation lookup level · e8719552
      Antonio Nino Diaz authored
      Instead of hardcoding a level 1 table as the base translation level
      table, let the code decide which level is the most appropriate given
      the virtual address space size.
      
      As the table granularity is 4 KB, this allows the code to select
      level 0, 1 or 2 as base level for AArch64. This way, instead of
      limiting the virtual address space width to 39-31 bits, widths of
      48-25 bit can be used.
      
      For AArch32, this change allows the code to select level 1 or 2
      as the base translation level table and use virtual address space
      width of 32-25 bits.
      
      Also removed some unused definitions related to translation tables.
      
      Fixes ARM-software/tf-issues#362

      AArch32: Add translation table library support · b2bca61d
      Soby Mathew authored
      This patch adds translation library supports for AArch32 platforms.
      The library only supports long descriptor formats for AArch32.
      The `enable_mmu_secure()` enables the MMU for secure world with
      `TTBR0` pointing to the populated translation tables.
