[U-Boot] [PATCH] dts: re-write dts/Makefile more simply with Kbuild

[Masahiro Yamada]

Hello Simon,


I saw the patch you posted
http://patchwork.ozlabs.org/patch/315846/
and I understood what you want to do.
(But I don't like to search similar device trees
with file name prefixes.)

Do you like ARM Linux style?
  dtb-$(CONFIG_EXYNOS5) += exynos5250-arndale.dtb \
        exynos5250-snow.dtb \
        exynos5250-smdk5250.dtb \
        exynos5420-smdk5420.dtb

Please check v2.

I vote for removal of ./u-boot.dts
because I do not want to have many copies.

If we adopt multiple DTBs generation, we will have three copies:
  - arch/arm/dts/exynosXXX.dtb
  - dts/dt.dtb
  - ./u-boot.dtb

But, if you really need a DTB at the top directory,
I can revive u-boot.dtb at version 3.

Good catch!
I fixed it at v2. Thanks.
