From: Rick Chen Date: Wed, 4 Dec 2019 06:52:46 +0000 (+0800) Subject: Use dts support from U-Boot via OF_SEPARATE instead of depending from opensbi. X-Git-Tag: v2020.01-rc5~6^2~14 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=31fbf6032ddd9b968b1ca102f71fe7f42fabf58a;p=oweals%2Fu-boot.git Use dts support from U-Boot via OF_SEPARATE instead of depending from opensbi. This would help to make the necessary changes in drivers and device trees in U-Boot tree itself. This feature would also be helpful to not pass dtb during opensbi builds.
