Author: adrian Date: Mon May 16 23:56:31 2016 New Revision: 299993 URL: https://svnweb.freebsd.org/changeset/base/299993 Log: [mips] Improve MIPS trampoline code This patch fix trampoline build. inckern.S increases stack and calls _startC of elf_trampoline, so inckern.S should be called before elf_trampoline. gcc4.2 puts text (code) into image according to order of source files in this call, so order has changed. In addition make will install trampoline kernel. It allows to use kernel for firmware build.
