---+++Required ARM Patches
   * Remove all externs from .c files - see esp. davinci.
   * Remove -msoft-float for all ARM boards/cpus - floating point is deprecated, although the ELDK tools are built with this option. <br>
     Code may be built locally with this option to allow local use of floating point.
   * The tag start.S::reset is confusing - all to be renamed start_code. 
   * Files named lowlevel_init.S should contain BOARD initialisation code & be located in the corresponding board directory <br>
     There are some under cpu. Any CPU initialisation code should be moved to the cpu_init_crit function in the corresponding cpu start.S file <br>
     or the start_code in that file.
   * cmc_pu2 && mp2usb use at91 defines ? should they ?
   * Recode all <br>
     *sub rx, rx, #CONSTANT* <br> 
     with regard to possible values of #CONSTANT <br>
     - must be 8 bit rotated in 32. <br>
     ? Provide an ifdef to allow smaller code when constant is acceptable ? <br>
     ? What expansion will occur if just all coded to allow any value     ?
   * Consolidate all the arm sizes.h <br>
     With the aim of replacing all SZ_xx macros with e.g (xx * 1024 * 1024))
   * Use *r7* for the gd pointer, rather than *r8*
      * *r8* is banked - not available in FIQ handlers without additional code
      * *r7* fits into Thumb/Thumb-2 instructions
      * Future ARM architectures may have similar constraints
   * Remove the unused S_R&lt;regnum&gt; defines throughout ARM code
   * Exception vectors incorrect in many files
   * General timer routines incorrect esp TIMER_LOAD_VAL
   * Implement weak, architecture specific, cache functions in lib_arm to allow 
     their removal from various cpu files.
   * Implement weak reset_cpu function in lib_arm to allow removal from cpu files.
