There are various reasons, like: - The device tree describes the platform, so it can also be used by the linux kernel for configuration (no separate dtb needed) - Properties are not hardcoded in the u-boot code - Slightly different hardware deviations do not require significant code changes (like #ifdef or even new platdatas), just a new dts and Kconfig adjustments It's also mentioned in Simon Glass's talk about DM: https://events.linuxfoundation.org/sites/events/files/slides/Order%20at%20last%20-%20U-Boot%20driver%20model%20slides%20(2).pdf _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
