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