I forgot:
&gpio2 {
/*
* The Qseven BIOS_DISABLE signal on the PX30-µQ7 keeps the
on-module
* eMMC powered-down initially (in fact it keeps the reset signal
* asserted). BIOS_DISABLE_OVERRIDE pin allows to re-enable eMMC.
*/
bios_disable_override {
gpios = <RK_PB5 GPIO_ACTIVE_LOW>;
output-high;
line-name = "bios_disable_override";
gpio-hog;
};
};
Since I had this change in the bootloader that was enough during my
tests, but better not rely on the bootloader whenever/wherever possible :)
I'll wait a bit for reviews before sending a v2 just for that.
Cheers,
Quentin
