flashrom
To update or erase the BIOS
flash
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
offset.
For devices such as the complex programmable logic device
(CPLD) or
field
programmable gate arrays (FPGA),
gpiotool
accesses those devices to drive the GPIO lines using the standard bus
interfaces such as
i2c
,
mem
, or
pci
.
