I will send a series for the > bloblist handoff next week and I think you will all see what I mean. I think the alternative is that QEMU in U-Boot just can't be used for certain features.

It's generating a good and valid enough dtb for Linux, so it should be good enough for us in general. --=20 Tom --pVF9EYSGkiif4dMH Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQGzBAABCgAdFiEEGjx/cOCPqxcHgJu/FHw5/5Y0tywFAmF5nMoACgkQFHw5/5Y0 tyz+wAv/dly234YsjqU4iqeUERxgfuAppQoK28yAJiw5cXekTdEAdpNfbAiGDZD9 124kercVWvN9v19Cl0vzeZjJ0l1IS4daFPKabEVDTx0cdxBgjpxAa5+HqvsV2Ics SyqgDuFoGCg0n4YQpm1gN88gmetWMqEdBuYtxOa+5ilaoAd/8N8U1OZ8ymIG9a2J wrysZtASoN3J9KsL2ZpiohaZwcA1/HMjyEV+HexDOqABBUIJpNQvKvWjjwOFW9el BdGQSSjgyL5hO8v1/eLCLdg40aYk7tdOPB1aXDOm5q9CU9Qjmk7v0AhZ+yIcGNqJ gK5pNwM22fLtCGW5MCau9YMRy+rg8KHDWI89nUDXa09fw/kIUGp3rn7TJ6dWvmkN QpcRBmEa3b1Y+DVwAx6+mB2n8wJ1GGkpzaXpy14M4OYF+svxWBR7GxcqgvQs3tv8 o2weLz4n0Kv0zYffcR9zBIWtwd4nkRl/w+/DfH6UnJ7YHKav1rJWzR3lkRK9n8Dp 4v6pkTQ8 =8ply -----END PGP SIGNATURE----- --pVF9EYSGkiif4dMH--
