On the NIOS2 and Xtensa architectures, we do not have CONFIG_SYS_TEXT_BASE set. This is a strict migration of the current values into the defconfig and removing them from the headers. I did not attempt to add more default values in and for now will leave that to maintainers. Signed-off-by: Tom Rini <trini@konsulko.com>
