[OpenPower-Firmware] How to convert PNOR to HPM? (was How risky is uploading self-compiled PNOR for Habanero?)

[Werner Fischer]

And I have another question: how can I convert the habanero_update.pnor
file that I get to a "hpm" file (which the update procedure of the BMC
webinterface is expecting when I want to do a firmware upgrade)?

PS: after compiling I got the following files:
        wfischer at tpw:~/git/op-build/output/images$ ls -lah
        total 224M
        drwxr-xr-x 2 wfischer wfischer 4,0K Nov 17 18:45 .
        drwxrwxr-x 7 wfischer wfischer 4,0K Nov 17 18:25 ..
        -rwxr-xr-x 1 wfischer wfischer  40K Nov 17 18:31 cappucode.bin

        -rwxr-xr-x 1 wfischer wfischer  32M Nov 17 18:45
        habanero_update.pnor

        -rw-r--r-- 1 wfischer wfischer  51M Nov 17 18:43 rootfs.tar
        -rwxr-xr-x 1 wfischer wfischer 979K Nov 17 18:44 skiboot.lid
        -rwxr-xr-x 1 wfischer wfischer 244K Nov 17 18:44 skiboot.lid.xz
        -rw-r--r-- 1 wfischer wfischer  15M Nov 17 18:43 zImage.epapr
        wfischer at tpw:~/git/op-build/output/images$ 

Thanks in advance for any feedback,
best regards,
Werner
