xtensa: drop unused sections and remapped reset handlers 2015-11-03T14:19:39+00:00 Max Filippov jcmvbkbc@gmail.com 2015-10-16T15:30:37+00:00 0d848afe117ac3e31b9d57b65553ff18ef9d288f There are no .bootstrap or .ResetVector.text sections linked to the vmlinux image, drop these sections from vmlinux.ld.S. Drop RESET_VECTOR_VADDR definition only used for .ResetVector.text. Drop remapped copies of primary and secondary reset vectors, as modern gdb don't have problems stepping through instructions at arbitrary locations. Drop corresponding sections from the corresponding linker scripts. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
