will SPI flash GD25LB128D (GD25LB128DSIG) be soon supported?

[Stefan Priehse]

This is the bios chip on ASUS ROG STRIX B450-F GAMING mainboard.

This should be the data sheet of this family of SPI flash chips.
  https://www.gigadevice.com/flash-memory/gd25lb128d/

I tried to connect it to a raspberry pi-4 with SOIC test clip and 1,8v power supply and logic-level converter,
  but flashrom v0.9.9-r1954 on Linux 4.19.105-v8-28 (aarch64)
  only found:
  flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=1000
  "...
  Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI) on linux_spi.
  Probing for Generic unknown SPI chip (REMS), 0 kB: REMS returned 0xc0 0x01. probe_spi_rems: id1 0xc0, id2 0x1
  Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI).
  ===
  This flash part has status NOT WORKING for operations: PROBE READ ERASE WRITE
  ..."

I saw in newest version https://github.com/flashrom/flashrom/blob/master/flashchips.h
  this chip is still not listed. So probably also not supported in newest development version.

You could try adding its' definitions to flashchips.c / flashchips.h ,
using the definitions or other GigaDevice chips as the base and
datasheet if available. Hopefully this would be more simple than it
seems for you. Then you could submit a working patch.
