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 Signed-off-by: Thibaut VARENE <varenet@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
