On the ThinkPad T480, -we have no nvram and, due to coreboot's design, we therefore -have no option table, so the default setting is enabled. - -In my testing, this seems to be that the system will turn on -after a power failure. If your ThinkPad was previously in a state -where it wouldn't turn on when plugging in the power, it'd be fine. - -If your battery ran out later on, this would be triggered and -your ThinkPad would permanently turn on, when plugging in a charger, -and there is currently no way to configure this behaviour. - -We currently only use the common SoC PMC code on the ThinkPad -T480, T480s and the Dell OptiPlex 3050 Micro, at the time of -this patch, and it is desirable that the system be set to power -off after power fail anyway. - -In some cases, you might want the opposite, for example if you're -running a server. This will be documented on the website, for that -reason. - -Signed-off-by: Leah Rowe <info@minifree.org> ---- - src/soc/intel/common/block/pmc/pmclib.c | 36 +++---------------------- - 1 file changed, 4 insertions(+), 32 deletions(-) - -diff --git a/src/soc/intel/common/block/pmc/pmclib.c b/src/soc/intel/common/block/pmc/pmclib.c -index 64b9bb997c..7823775bcb 100644 ---- a/src/soc/intel/common/block/pmc/pmclib.c -+++ b/src/soc/intel/common/block/pmc/pmclib.c -@@ -776,38 +776,10 @@ void pmc_clear_pmcon_sts(void) - - void pmc_set_power_failure_state(const bool target_on) - { -- const unsigned int state = get_uint_option("power_on_after_fail", -- CONFIG_MAINBOARD_POWER_FAILURE_STATE); -- -- /* -- * On the shutdown path (target_on == false), we only need to -- * update the register for MAINBOARD_POWER_STATE_PREVIOUS.
