Package the ability to log kernel crashes to 'ramoops' pstore files into RAM in /sys/fs/pstore Reference to the ramoops admin guide in upstream Linux: https://www.kernel.org/doc/html/v5.10/admin-guide/ramoops.html The files in RAM survive a warm reboot, but not a cold reboot. Note: kmod-ramoops selects kmod-pstore and kmod-reed-solomon. The feature can be used by selecting the kmod-ramoops and adding a ramoops reserved-memory definition to the device DTS. Example from R7800: reserved-memory { rsvd@5fe00000 { reg = <0x5fe00000 0x200000>; reusable; }; ramoops@42100000 { compatible = "ramoops"; reg = <0x42100000 0x40000>; record-size = <0x4000>; console-size = <0x4000>; ftrace-size = <0x4000>; pmsg-size = <0x4000>; }; }; If no definition has been made in DTS, no crash log is stored for the device.
