Why does device tree change how things work now? The get_board_rev() function currently deals with this. It doesn't look like rpi_board_rev is used anywhere else. > absolutely must be done, please note that there are many more RPi models > than there are currently DT files for in the upstream kernel.

I've only added two - one for Raspberry Pi, and one for Raspberry Pi 2 (patches not sent yet, but at u-boot-dm/rpi-working) Regards, Simon _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
