/* 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.
