[flashrom] WinBond Chip Support

[Jordan Hill]

Hello there,

I have a Dell Inspiron 5559 Laptop which contains a Winbond 25Q128FVSQ
Chip. I tried running flashrom natively on the laptop and got the usual EC
warning so i stopped there. I then desoldered the SMD chip off the
motherboard and hooked it up to a RPI and connected it through the SPI
protocol. Flashrom then recognized it as a "Generic" flash chip and would
not allow the data to be read as it was still unrecognized. Unfortunately I
do not have any logs. I believe that this chip is on the list of supported
hardware yet it was not recognized in flashrom. I am using the latest
version as of April 18th 2018. Any suggestions or help would be appreciated.

Thank You

did you connect all input pins of the flash chip? A common error is to
leave /HOLD and /WP floating. But they need a defined state. /HOLD has
to be pulled up (towards VCC). /WP up too (might as well be down depen-
ding on the chip's configuration, but up always works).
