1 | /* ld script to make the Linux/CRIS kernel |
2 | * Authors: Bjorn Wesen (bjornw@axis.com) | |
3 | * | |
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. | |
