This is why, sooner rather than later I believe, we need to come up with a good way to pass device trees in and around, asap. An SPL that contains a device tree for the correct board (and passes along to U-Boot which could in turn pass along to the kernel if it's a full tree) would solve your problem, yes? - -- Tom -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iQIcBAEBAgAGBQJQs+R7AAoJENk4IS6UOR1WM14P/0ZUEk8E7+Qwmn1aGkXfRZBC 3cN06jWVBfio31Ic1HMJJJNoOsHgGLuV9hRI9Gl0U/9o4pvVLtI6tfIQB0rHdkDr HYwiAeq6fuJV/HE+oOsEt+DKn/NZsQd3U45TL1oK5A53Bfqh56LDuieqJnZ1FE2F 2G2Bi3VfMaP/Fx4VhIJpDrE3UkWZH4uzkjV7B2BeCfPaY02cEUbIsCYksPAUPxat E9lXgVYE+HThHPfYVZOcDpf+R3NPwfNqT0y7d256bMmxQW6C6W6sJjK0JsmeEQWm M+drhxaWXihtQ5pOUxSSgW5XOTbvdtJDA+vVLegPG0fjNKpAJStEsYPy2QJeZEzQ HtTLX7EPuKk55t+vUVB5k5e6BIT8WUSu2nzxi4N9D6pZgE80DdeTIw6Ez+KfR10x MiPaFpvLq3db7fzIg2GAoCiNppcimZPSBISRZyrUsZTDyXtsEgDqTqOOAcvmO6lY 9nHIFGAHG4QDW76Y1dW4/KkqI9TIwm6oph31sL/IgmhQ0R0TlwTKxV71ia4jwSOg qSs3O2qK+LvgNCNqPgeLljRML2PdyoWsA17sTcmsh4Na9B1O0rRFEbFBCAiCZsug toacIVgySbKdLucCHxcD7vS7IGSioVOsa+fPa7wSlKySLMcBxeooMqxR1+cqXsh7 /Kf4StcSqoMr8I7Mitgy =uk8l -----END PGP SIGNATURE----- _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
