No. I have splitted this series to 'ath-79 gpio' and 'ath-79 pbl' series.
I have to test 'ath-79 pbl' series more carefully.
Please apply today's 'ath-79 gpio' series (I have posted 'ath-79 gpio' series
several hours ago).

Also please change both 'SPL' -> 'SBL' in this commit message from pengutronix/next branch:

    MIPS: refactor SPL start.S code

    This commit removes code duplication by using
    MIPS PBL macros in the SPL start.S file.
