[coreboot] coreboot image signature

[Zoran Stojsavljevic]

Hello John,

Thank you for guiding me. I used last 5 years (while being with INTEL)
mainly HxD (for WIN). Did not used very long hex editors for Linux. Here it
is (your suggestion):
_______

[zoran at localhost tools]$ dnf whatprovides hexedit
hexedit-1.2.13-8.fc24.x86_64 : A hexadecimal file viewer and editor
Repo        : fedora

[root at localhost tools]$ sudo dnf install hexedit-1.2.13-8.fc24.x86_64
