After having tried all 4 options of flashchips on my bios, they will all fail to erase and then finally write the new Coreboot ROM I've compiled.
I have changed power sources, methods of powering the Pi3, as well as all the different SPI speeds.
Found Macronix flash chip "MX25L6405" (8192 kB, SPI) on linux_spi.Found Macronix flash chip "MX25L6405D" (8192 kB, SPI) on linux_spi.Found Macronix flash chip "MX25L6406E/MX25L6408E" (8192 kB, SPI) on linux_spi.Found Macronix flash chip "MX25L6436E/MX25L6445E/MX25L6465E/MX25L6473E" (8192 kB, SPI) on linux_spi.Multiple flash chip definitions match the detected chip(s): "MX25L6405", "MX25L6405D", "MX25L6406E/MX25L6408E", "MX25L6436E/MX25L6445E/MX25L6465E/MX25L6473E"
I noticed while Googling flashrom troubleshooting it said something about 'turning write-protection
off'. I have absolutely no issues reading the BIOS, and I have md5sum checked it multiple times and they all give the same reading. It seems as if something else is missing that's not allowing the chip to be erased.
Here is a log I've included from one of the many failed attempts:

Checking if anything has changed.Reading current flash chip contents... done.Good, writing to the flash chip apparently didn't do anything.Please check the connections (especially those to write protection pins) betweenthe programmer and the flash chip. If you think the error is caused by flashromplease report this on IRC at chat.freenode.net (channel #flashrom) ormail flashrom at flashrom.org, thanks!
