/* ld script to make the Linux/CRIS kernel
* Authors: Bjorn Wesen (bjornw@axis.com)
*
* 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.
