/* ld script to make the Linux/CRIS kernel
 * Authors: Bjorn Wesen ([e-mail])
 *
 * It is VERY DANGEROUS to fiddle around with the symbols in this
 * script. It is for example quite vital that all generated sections
 * that are used are actually named here, otherwise the linker will
 * put them at the end, where the init stuff is which is FREED after
 * the kernel has booted.
