[U-Boot] [PATCH v3 09/12] x86: Make chromebook_link the default board for coreboot
Bin Meng
bmeng.cn at gmail.com
Tue Jan 6 05:20:35 CET 2015
Change SYS_CONFIG_NAME and DEFAULT_DEVICE_TREE to chromebook_link
which is currently the only real board officially supported to run
U-Boot loaded by coreboot.
Note the symbolic link file chromebook_link.dts is deleted and
link.dts is renamed to chromebook_link.dts.
To avoid multiple definition of video_hw_init, the CONFIG_VIDEO_X86
define needs to be moved to arch/x86/cpu/ivybridge/Kconfig.

Changes in v3:
- Move CONFIG_VIDEO_X86 to drivers/video/Kconfig
Changes in v2:
- New patch to make chromebook_link the default board for coreboot
