main/blobtools: Allow blob signing

Certain recent Asus Tegra SoC based devices (tf201, tf300, tf700) only accept signed blobs, this was implemented upstream but seems that some lines got deleted so it wasn't being signed which was fine for devices (Asus tf101) that didn't require it.

To reuse the existing setup I added a patch for blobtools that let us enable singing via optional flag, this same flag is only enabled when device has deviceinfo_bootimg_blobpack="sign" existing devices (tf101) use deviceinfo_bootimg_blobpack="true" which shouldn't be affected by these changes.

After this MR there is plans to send MR for initial asus-tf201 bringup.

Thanks for making this @IonAgorria! Besides some nitpicks, this looks good.

We should update https://wiki.postmarketos.org/wiki/Deviceinfo_reference when this gets merged.

Thanks for the update, @IonAgorria! Also sorry that it took me some time to get back to this.

I've imported your repo here: https://gitlab.com/postmarketOS/asus-transformer-blobtools

And tagged a release: https://gitlab.com/postmarketOS/asus-transformer-blobtools/-/tags/1.1.0

(1.0.0 is the one from github)

So now I suggest to update the blobtools package:

• use this 1.1.0 version
• rename it to asus-transformer-blobtools

Awesome, I made the change of package name and APKBUILD modifications in same commit but if it's preferred to be separate commits I can change it.

That's fine. Let's get this merged soon. I'm just wondering about that new mv line.

Thanks for the update, @IonAgorria!

I'll squash the two patches that modify the blobtools package into one, fix the checksums and then I'll merge it.

EDIT: oh, no need to squash. I didn't read the commit messages properly.
