+  Version History
+  ---------------
+  -v2.4.4 (October 13 2008) 
+        * Corrected minor syntactic bug on statistic gathering code.
+          Reported by Tim Cussins and P. Mantegazza.
+        
+  -v2.4.3 (July 30 2008) 
+        * Minor fixes to compile with the greenhills compiler. 
+          Reported by "Kaya, Sinan SEA" <sinan.kaya@siemens.com>
+        * Small change in the license in order to include TLSF in the RTEMS 
+          project.
+        
+  -v2.4.2 (May 16 2008) (Herman ten Brugge)
+        * Memory usage statistics added again, with cleaner and more compacted
+          code. 
+        
+  -v2.4.1 (April 30 2008)
+        * Fixed a bug in the tlsf_realloc function: init the pool automatically
+          on the first call. 
+          Reported by: Alejandro Mery <amery@geeks.cl>
+        
+  -v2.4  (Feb 19 2008) 
+        * "rtl_*" functions renamed to "tlsf_*".
+        * Added the add_new_area function to insert new memory areas to an
+          existing memory pool.
+        * A single TLSF pool can manage non-contiguous memory areas.
+        * Support for mmap and sbrk added.
+        * The init_memory_pool is not longer needed when used on a system
+          with mmap or sbrk.
+        * Removed the get_used_size counting.The same functionality can be
+        implemented outside the TLSF code.
+        
+  -v2.3.2 (Sep 27 2007) 
+        * Minor cosmetic code improvements.
+
+  -v2.3.1 (Jul 30 2007)
+        * Fixed some minor bugs in the version 2.3. Herman ten Brugge
+             <hermantenbrugge@home.nl>
+        
+  -v2.3 (Jul 28 2007) Released a new version with all the contributions 
+        received from Herman ten Brugge <hermantenbrugge@home.nl> 
+        (This is his summary of changes in the TLSF's code):
+        * Add 64 bit support. It now runs on x86_64 and solaris64.
+        * I also tested this on vxworks/32 and solaris/32 and i386/32 
+          processors.
+        * Remove assembly code. I could not measure any performance difference
+          on my core2 processor. This also makes the code more portable.
+        * Moved defines/typedefs from tlsf.h to tlsf.c
+        * Changed MIN_BLOCK_SIZE to sizeof (free_ptr_t) and BHDR_OVERHEAD to
+         (sizeof (bhdr_t) - MIN_BLOCK_SIZE). This does not change the fact
+         that the minumum size is still sizeof (bhdr_t).
+        * Changed all C++ comment style to C style. (// -> /* ... *./)
+        * Used ls_bit instead of ffs and ms_bit instead of fls. I did this to
+          avoid confusion with the standard ffs function which returns
+          different values.
+        * Created set_bit/clear_bit fuctions because they are not present
+          on x86_64.
+        * Added locking support + extra file target.h to show how to use it.
+        * Added get_used_size function
+        * Added rtl_realloc and rtl_calloc function
+        * Implemented realloc clever support.
+        * Added some test code in the example directory.
+
+        -- Thank you very much for your help Herman!
+
+  -v2.2.1 (Oct 23 2006)
+        * Support for ARMv5 implemented by Adam Scislowicz
+          <proteuskor@gmail.com>. Thank you for your contribution.
+
+  - v2.2.0 (Jun 30 2006) Miguel Masmano & Ismael Ripoll.
+
+        * Blocks smaller than 128 bytes are stored on a single
+          segregated list. The already existing bits maps and data
+          structures are used.
+        * Minor code speed-up improvements.
+        * Worst case response time both on malloc and free improved.
+        * External fragmantation also improved!.
+        * Segragared lists are AGAIN sorted by LIFO order. Version
+          2.1b was proven to be no better than 2.1.
+
+  - v2.1b: Allocation policy has been always a LIFO Good-Fit, that
+           is, between several free blocks in the same range, TLSF will
+           always allocate the most recently released. In this version of
+           TLSF, we have implemented a FIFO Good-Fit. However,
+           fragmentation doesn't seems to be altered so is it worth it?.
+        
+  - v2.1:  Realloc and calloc included again in TLSF 2.0.
+
+  - v2.0:  In this version,  TLSF has been programmed  from scratch.
+           Now the allocator is provided as an unique file. Realloc and
+           calloc are not longer implemented.
+
+
+  - v1.4:  Created  the   section  "Version  History".   Studied  real
+           behaviour of actual applications (regular applications tend
+           to require small memory blocks (less than 16 bytes) whereas
+           TLSF is  optimised to  be used with  blocks larger  than 16
+           bytes: Added special lists to deal with blocks smaller than
+           16 bytes.
+
+
+  - v1.3: Change  of concept, now  the main TLSF structure  is created
+          inside of  the beginning  of the block  instead of  being an
+          static  structure, allowing  multiple TLSFs  working  at the
+          same time.  Now, TLSF uses specific processor instructions to
+          deal with bitmaps.  TLSF sanity functions added to find TLSF
+          overflows.  The  TLSF code will not  be RTLinux-oriented any
+          more.
+
+  - v1.1 ...  v1.2: Many little  bugs fixed, code cleaned and splitted
+                    in several files because of cosmetic requirements.
+                    Starting     from    TLSF    v1.1,     MaRTE    OS
+                    (http://marte.unican.es)  uses the  TLSF allocator
+                    as its default memory allocator.
+
+  - v0.1 ... v1.0: First  implementations were created for testing and
+                   research purposes.  Basically TLSF is implemented to 
+                   be used by  RTLinux-GPL  (www.rtlinux-gpl.org),  so  
+                   it  is RTLinux-oriented.

+
+TLSF Memory Storage allocator implementation.
+Version 2.4 Feb 2008
+
+Authors: Miguel Masmano, Ismael Ripoll & Alfons Crespo.
+Copyright UPVLC, OCERA Consortium.
+
+TLSF is released in the GPL/LGPL licence. The exact terms of the licence
+are described in the COPYING file.
+
+This component provides basic memory allocation functions:
+malloc and free, as defined in the standard "C" library.
+
+This allocator was designed to provide real-time performance, that is:
+1.- Bounded time malloc and free.
+2.- Fast response time.
+3.- Efficient memory management, that is low fragmentation.
+
+
+The worst response time for both malloc and free is O(1).
+
+
+
+How to use it:
+
+This code  is prepared to  be used as  a stand-alone code that  can be
+linked with a regular application or  it can be compiled to be a Linux
+module  (which  required the  BigPhysicalArea  patch).  Initially  the
+module was  designed to  work jointly with  RTLinux-GPL, but it  can be
+used as a stand alone Linux module.
+
+When compiled as a regular linux process the API is:
+
+Initialisation and destruction functions
+----------------------------------------
+
+init_memory_pool may be called before any request or release call:
+
+- size_t init_memory_pool(size_t, void *);
+- void destroy_memory_pool(void *);
+
+Request and release functions
+-----------------------------
+
+As can be seen, there are two functions for each traditional memory
+allocation function (malloc, free, realloc, and calloc). One with the
+prefix "tlsf_" and the other with the suffix "_ex". 
+
+The versions with the prefix "tlsf_" provides the expected behaviour,
+that is, allocating/releasing memory from the default memory pool. The
+default memory pool is the last pool initialised by the
+init_memory_pool function.
+
+On the other hand, the functions with the prefix "_ex" enable the use of several memory pools.
+
+- void *tlsf_malloc(size_t);
+- void *malloc_ex(size_t, void *);
+
+- void tlsf_free(void *ptr);
+- void free_ex(void *, void *);
+
+- void *tlsf_realloc(void *ptr, size_t size);
+- void *realloc_ex(void *, size_t, void *);
+
+- void *tlsf_calloc(size_t nelem, size_t elem_size);
+- void *calloc_ex(size_t, size_t, void *);
+
+EXAMPLE OF USE:
+
+char memory_pool[1024*1024];
+
+{
+        ...
+
+        init_memory_pool(1024*1024, memory_pool);
+
+        ...
+        
+        ptr1=malloc_ex(100, memory_pool);
+        ptr2=tlsf_malloc(100); // This function will use memory_pool
+        
+        ...
+
+        tlsf_free(ptr2);
+        free_ex(ptr1, memory_pool);
+}
+
+Growing the memory pool
+-----------------------
+
+Starting from the version 2.4, the function add_new_area adds an
+memory area to an existing memory pool.
+
+- size_t add_new_area(void *, size_t, void *);
+
+This feature is pretty useful when an existing memory pool is running
+low and we want to add more free memory to it.
+EXAMPLE OF USE:
+
+char memory_pool[1024*1024];
+char memory_pool2[1024*1024];
+
+{
+        ...
+
+        init_memory_pool(1024*1024, memory_pool);
+
+        ...
+        
+        ptr[0]=malloc_ex(1024*256 memory_pool); 
+        ptr[1]=malloc_ex(1024*512, memory_pool); 
+        add_new_area(memory_pool2, 1024*1024, memory_pool);
+        // Now we have an extra free memory area of 1Mb
+        // The next malloc may not fail
+        ptr[2]=malloc_ex(1024*512, memory_pool); 
+        
+        ...
+
+}
+
+
+SBRK and MMAP support
+---------------------
+
+The version 2.4 can use the functions SBRK and MMAP to _automatically_
+growing the memory pool, before running out of memory.
+
+So, when this feature is enabled, unless the operating system were out
+of memory, a malloc operation would not fail due to an "out-of-memory"
+error.
+
+To enable this support, compile tlsf.c with the FLAGS -DUSE_MMAP=1 or
+-DUSE_SBRK=1 depending on whether you want to use "mmap" or "sbrk" or both.
+
+** By default (default Makefile) this feature is enabled.
+
+EXAMPLE OF USE:
+
+gcc -o tlsf.o -O2 -Wall -DUSE_MMAP=1 -DUSE_SBRK=1
+
+---
+
+If the sbrk/mmap support is enabled and we are _only_ going to use one
+memory pool, it is not necessary to call init_memory_pool
+
+EXAMPLE OF USE (with MMAP/SBRK support enabled):
+
+{
+        ...
+        
+        ptr2=tlsf_malloc(100); // This function will use memory_pool
+        
+        ...
+
+        tlsf_free(ptr2);
+}

+To do list
+==========
+
+* Add mmap/sbrk support (DONE - V2.4).
+
+* TLSF rounds-up request size to the head of a free list.
+        It has been shown to be a good policy for small blocks (<2048).
+        But for larger blocks this policy may cause excesive fragmentation.
+        A deeper analisys should be done.
