PS2, Line 9: Gpio 88 toggle is used as write protection disable/enable now
           : and we need that to happen at the initialization of programmer.
> Happy to +2 this however I still would like to see a better explanation as to why.

Since Shiyu is unavailable and this seems to fix a bug where 'Block protection could not be disabled' I think we can accept this and press forwards.
