Some chips that are sourced from ebay, aliexpress and similar sources are not what they seem.
A popular chip reports JEDEC ID: C2 25 38 even though it isn't a genuine chip. It doesn't support quad i/o mode.
C2 25 38
One way to solve this is to read a known value on the flash. If this fails, fall back using the generic SPI driver and try again.
Ideally we should probe in a better way.
