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.
