Steve Markgraf uploaded patch set #6 to this change.
programmer: Add bitbanging programmer driver for Linux libgpiod
With this driver, any single board computer, old smartphone, etc. with
a few spare GPIOs can be used for flashrom.
Tested by reading of a 2048 kB flash chip on a Qualcomm MSM8916 SoC
@800 MHz, ran the following command:
time flashrom -p linux_gpiod:gpiochip=0,cs=18,sck=19,mosi=13,miso=56 -r test.bin
This command uses /dev/gpiochip0 with the specified GPIO numbers for the
SPI lines. All arguments are mandatory.
Output:
[...]
Found GigaDevice flash chip "GD25LQ16" (2048 kB, SPI) on linux_gpiod.
[...]
