Subject: [U-Boot] [PATCH v3] MIPS: add initial infrastructure for device-tree files
Date: Mon, 11 Jan 2016 17:48:20 +0100 [thread overview]
Message-ID: <1452530900-22860-1-git-send-email-daniel.schwierzeck@gmail.com> (raw)
In-Reply-To: <1450564990-17333-1-git-send-email-daniel.schwierzeck@gmail.com>
Prepare sub-folder for device-tree files. Make support for
device-tree on MIPS available in Kbuild/Kconfig.

Changes in v3:
- keep section .dtb.init.rodata during link in case of CONFIG_OF_EMBED, .dtb only
does not work
Changes in v2:
- add arch/mips/dts to clean list in dts/Makefile
- keep section .dtb during link in case of CONFIG_OF_EMBED
