[PARISC] PDC_CHASSIS is implemented on all machines

Browse Source 
This patch removes a limitation of the original code, so that CHASSIS
codes can be sent to all machines. On machines with a LCD panel, this
code displays "INI" during bootup, "RUN" when the system is booted and
running, "FLT" when a panic occurs, etc.

This part of the code can be enabled/disabled through CONFIG_PDC_CHASSIS

This patch also adds minimalistic support for Chassis warnings, through
a proc entry '/proc/chassis', which will reflect the warnings status (PSU
or fans failure when they happen, NVRAM battery level and temperature
thresholds overflows).

This part of the code can be enabled/disabled through CONFIG_PDC_CHASSIS_WARN

Say Y here if you want to enable support for the LED State front
panel as found on E class, and support for the GSP Virtual Front
Panel (LED State and message logging) as found on high end
servers such as A, L and N-class.
This has nothing to do with Chassis LCD and LED support.
Say Y here if you want to enable support for Chassis codes.
That includes support for LED State front panel as found on E
class, and support for the GSP Virtual Front Panel (LED State and
message logging) as found on high end servers such as A, L and
N-class.
This driver will also display progress messages on LCD display,
such as "INI", "RUN" and "FLT", and might thus clobber messages
shown by the LED/LCD driver.
This driver updates the state panel (LED and/or LCD) upon system
state change (eg: boot, shutdown or panic).

This will add a proc entry '/proc/chassis' giving some information
about the overall health state of the system.
This includes NVRAM battery level, overtemp or failures such as
fans or power units.
