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