   1/* ld script to make the Linux/CRIS kernel

   4 * It is VERY DANGEROUS to fiddle around with the symbols in this
   5 * script. It is for example quite vital that all generated sections
   6 * that are used are actually named here, otherwise the linker will
   7 * put them at the end, where the init stuff is which is FREED after
   8 * the kernel has booted.
