MIPS: Clean up arch/mips/boot/compressed/ld.script
- Remove unused symbols: _fdata, _text; only _edata and _end are needed by head.S - Remove unused sections: .sbss, .stab, .gptab.sdata, .gptab.sbss - Change the alignment to 16 bytes to ensure it is greater than any fundamental type of a MIPS compiler. - Clean up comments Signed-off-by: Wu Zhangjin <wuzhangjin@gmail.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/1381/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
