Hello Felix Singer, build bot (Jenkins), Thomas Heijligen, Angel Pons, Anastasia Klimchuk,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/flashrom/+/71801
to look at the new patch set (#5).
Change subject: programmer: Add bitbanging programmer driver for Linux libgpiod ......................................................................
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. [...] real 1m 33.96s
