That's not what your property is saying, though - if it were just about handover between the bootloader and the kernel that'd be one thing but it's also got this additional possibility to instruct the kernel that the device must be either disabled or explicitly programmed. Having a property that just says "this FPGA is programmed" covers the handover case but this property does more than that. --YBGzgpgHAney5ErF Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBAgAGBQJUTn4qAAoJECTWi3JdVIfQ63kH/2i8gFq/EKKOgHea8XOh+ss7 nDfdO8UPUkA4Szj588ABrsmG6Vg0cgNJMX+oFKVWjiY+RkC3j1WBS/VNTN1cfG5W FnnTQKxAr15rW0PTnkO+pWNaB+PDaLv0m+WgDyUFzVUDhg0aOjwtBXlW93SAw+E7 9t0Xnc+RxoBZhJLLVa1iF/mqfwyNc09Q4QHFeMwa4o8WoOGVlAYfSYIVND/94wZw h2/JzF7dft5mU1YaxD63eE+lHIkP+pEV7CcV2XMcsQaM64PYTjwQM7h90Fx2R33h T0YCG4cOYtFXTPHiiOS1Ykg4/Uc0Tyz2F6hui0DXgBoYYsCs1y8bXY9hq9k9fik= =m35G -----END PGP SIGNATURE----- --YBGzgpgHAney5ErF-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
