[OpenPower-Firmware] Can't flash compiled image - Invalid PNOR image

[Patryk Duda]

Thanks for quick response.

I didn't know that there is such great tool like pflash.
It allowed me to update skiboot successfully.

What I had to do before updating was signing skiboot.lid.xz using
sb-signing-utils with default IBM keys.

Unfortunately problem with interrupts still persists.

Thanks,
Patryk
