907046 - Remove libnfc-nxp from B2G base manifest

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: NFC, defect)

Description

[Yoshi Cheng-Hao Huang [:allstars.chh][:allstarschh][:yoshi]]

Currently there are some devices which don't use libnfc-nxp as their NFC libraries. 
So we should remove libnfc-nxp from base manifest, and only enable it for some particular devices.
AFAIK, Nexus-S uses libnfc-nxp.

Michael, do you know what devices other than Nexus-S use libnfc-nxp?

thanks

No idea. However, if we're not planning to support libnfc-nxp, we can remove it regardless since it'll make no difference.

Oh, wait
From Nexus-4, there's also a library called libnfc_ndef.so, which seems from libnfc_nxp.

Yes, it's from libnfc-nxp, I think.

Sony Rhine devices do use NXP

Yes, and numerous other devices use nxp. If we wish to port Firefox OS to those devices (as per the new goal of porting ALL the things!) we will need to provide support here for nxp based nfc devices.
