ashrom
To update or erase the BIOS ash memory, the smbiostool uses flashrom.
gpiotool
The gpiotool controls the state of the GPIO lines from the CPU or any other device that drives the GPIO lines.
The CPU GPIO alines the map in Linux to /sys/class/gpio entries, which are manipulated through the standard read/write interfaces.
There is chip numbering to support multiple GPIO chips, or chips at an oset. For devices such as the complex programmable logic device
(CPLD) or eld programmable gate arrays (FPGA),
gpiotool accesses those devices to drive the GPIO lines using the standard bus
interfaces such as i2c, mem, or pci.
