+# 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
