ATAPI: STARTSTOPUNIT only eject/load media if powercondition is 0
The START STOP UNIT command will only eject/load media if
power condition is zero.
If power condition is !0 then LOEJ and START will be ignored.
From MMC (sbc contains similar wordings too)
The Power Conditions field requests the block device to be placed
in the power condition defined in
Table 558. If this field has a value other than 0h then the Start
and LoEj bits shall be ignored.
