-* This is one fun bit of code ...
-* Some easy listening music is suggested while trying to understand this
-* code e.g. Iron Maiden
-*
-* For anyone attempting to understand it :
-*
-* The core code is implemented here with simple stubs for memcpy()
-* memmove() and bcopy().
-*
-* All local labels are prefixed with Lmemcpy_
-* Following the prefix a label starting f is used in the forward copy code
-* while a label using b is used in the backwards copy code
-* The source and destination addresses determine whether a forward or
-* backward copy is performed.
-* Separate bits of code are used to deal with the following situations
-* for both the forward and backwards copy.
-* unaligned source address
-* unaligned destination address
-* Separate copy routines are used to produce an optimised result for each
-* of these cases.
-* The copy code will use LDM/STM instructions to copy up to 32 bytes at
-* a time where possible.
-*
-* Note: r12 (aka ip) can be trashed during the function along with
-* r0-r3 although r0-r2 have defined uses i.e. src, dest, len through out.
-* Additional registers are preserved prior to use i.e. r4, r5 & lr
-*
-* Apologies for the state of the comments;-)
