Attached is a patch to add GigaDevice's GD25QXX series of chips. I ran across the GD25Q80 variant in a promotional greeting card. I successfully read, erased and wrote to this particular chip . I added various other GigaDevice chips that I found on their website and marked them as untested. Of note is that in particular the GD25Q80 chip has two versions the base variant (that I have) and a 'B' variant. The apparent difference is that the 'B' variant has support for OTP regions, while the plain one does not. I believe they present the same identifier when queried, not sure what issues this poses, leaving in OTP did not impact the operation of my particular non 'B' variant chip. Here is a link to the root page containing datasheets for these chips:

Calibrating delay loop... delay loop is unreliable, trying to continue OK. Found Gigadevice flash chip "GD25Q80" (1024 kB, SPI) on rayer_spi. Reading old flash chip contents... done. Erasing and writing flash chip... Erase/write done. Verifying flash... VERIFIED.
