The state of this GPIO determines whether a factory reset has been
requested. If a physical switch is used, it can be high or low. During boot,
the software checks and records the state of this switch. If it is different
than the previous recorded state, then the read-write portions of memory are
reformatted.

The MCTP LPC driver was loaded by hacking up the compatible in the
devicetree node for KCS 4. With the introduction of the raw KCS driver
this hack is no-longer required. Use the regular compatible string for
KCS 4 and configure the appropriate SerIRQ.
The reset state of the status bits on KCS 4 is inappropriate for the
MCTP LPC binding. Switch to KCS 3 which has a different reset behaviour.

Input pin that indicates that the BMC is configured to boot with security
protections enforced.
Pulled up by default (secure). Placing the jumper will pull the pin down
(bypass security).
When in the secure boot state, it makes the EEPROM at 0x50 on bus 14
read only.

Tacoma and Rainier both have a line-names array that is too long:
gpio gpiochip0: gpio-line-names is length 232 but should be at most length 208
This was probably copied from an AST2500 device tree that did have more
GPIOs on the controller.

GPIOP7 is used in the Rainier design to manage the state of a
microcontroller elsewhere in the system but its ball, Y23, is the
driver of the heartbeat LED on the ast2600-evb and the SoC defaults Y23
at power-on to the pulse-train behaviour used to drive the LED. This
causes much confusion for the micro in the Rainier system, so hog the
line as early as possible.
