    There's currently driver/mtd/mtdoops.c, fs/pstore/, and
    drivers/staging/android/ram_console.c that do similar things
    as this. Did you investigate those for potentially modifying them to add
    this functionality ? If so what issues did you find?

    I have a arm MSM G1 with persistent memory at 0x16d00000 size 20000bytes..
    It's fairly simple you just have to ioremap the memory, but then it's good
    for writing.. Currently the android ram_console uses this. How would I
    convert this area for use with your changes?
