boot/lpc32xxcdl/lpc32xxcdl-2.11-libnosys_gnu.patch

   1 Fix compilation and eabi issues
   2
   3 Since we are not linking with libc anymore, we need to define our own memset,
   4 strlen and memcpy. Also, as we are using a *libc compiler, we need to "handle"
   5 exceptions (mostly division by 0) by defining raise() and
   6 __aeabi_unwind_cpp_pr0.
