+   Hi,
+
+   I recently finished a "memcpy" replacement and thought it might be useful for
+   others...
+
+   I've put some instructions and the code here:
+
+   http://www.rock-software.net/downloads/memcpy/
+
+   Hope it works for you as well as it did for me.

+libs/libc/misc/lib_crc32.c
+=========================
+
+   Copyright (C) 2010-2011 Gregory Nutt. All rights reserved.
+
+ The logic in this file was developed by Gary S. Brown:
+
+   COPYRIGHT (C) 1986 Gary S. Brown.  You may use this program, or code or tables
+   extracted from it, as desired without restriction.
+
+ First, the polynomial itself and its table of feedback terms.  The polynomial is:
+
+    X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
+
+ Note that we take it "backwards" and put the highest-order term in the lowest-order bit.
+ The X^32 term is "implied"; the LSB is the X^31 term, etc.  The X^0 term (usually shown
+ as "+1") results in the MSB being 1
+
+ Note that the usual hardware shift register implementation, which is what we're using
+ (we're merely optimizing it by doing eight-bit chunks at a time) shifts bits into the
+ lowest-order term.  In our implementation, that means shifting towards the right.  Why
+ do we do it this way?  Because the calculated CRC must be transmitted in order from
+ highest-order term to lowest-order term.  UARTs transmit characters in order from LSB
+ to MSB.  By storing the CRC this way we hand it to the UART in the order low-byte to
+ high-byte; the UART sends each low-bit to hight-bit; and the result is transmission bit
+ by bit from highest- to lowest-order term without requiring any bit shuffling on our
+ part.  Reception works similarly
+
+ The feedback terms table consists of 256, 32-bit entries.  Notes
+
+ - The table can be generated at runtime if desired; code to do so is shown later.  It
+   might not be obvious, but the feedback terms simply represent the results of eight
+   shift/xor operations for all combinations of data and CRC register values
+
+ - The values must be right-shifted by eight bits by the updcrc logic; the shift must
+   be u_(bring in zeroes).  On some hardware you could probably optimize the shift in
+   assembler by using byte-swap instructions polynomial $edb88320

+              This implementation of memcpy() is ANSI-C89 compatible.
+
+ The following configuration options can be set:
+
+   CONFIG_ENDIAN_BIG
+     Uses processor with big endian addressing. Default is little endian.
+
+   CONFIG_MEMCPY_PRE_INC_PTRS
+     Use pre increment of pointers. Default is post increment of pointers.
+
+   CONFIG_MEMCPY_INDEXED_COPY
+     Copying data using array indexing. Using this option, disables the
+     CONFIG_MEMCPY_PRE_INC_PTRS option.
+
+   CONFIG_MEMCPY_64BIT - Compiles memcpy for 64 bit architectures
