   1 ## @file
   2 #  Instance of Base Memory Library with some ARM vldm/vstm assembly.
   3 #
   4 #  This is a copy of the MdePkg BaseMemoryLib with the CopyMem and
   5 #  SetMem worker functions replaced with assembler that uses
   6 #  vldm/vstm (part of NEON SIMD, optional in ARMv7-A).
   7 #
   8 #  Note: You need to enable NEON in SEC to use this library
   9 #  // Enable NEON register in case folks want to use them for optimizations (CopyMem)
  10 #  mrc     p15, 0, r0, c1, c0, 2
  11 #  orr     r0, r0, #0x00f00000   // Enable VPF access (V* instructions)
  12 #  mcr     p15, 0, r0, c1, c0, 2
  13 #  mov     r0, #0x40000000       // Set EN bit in FPEXC
  14 #  msr     FPEXC,r0
