[PATCH 0/9] dts: Move to SoC-specific build rules

[Simon Glass]

U-Boot builds devicetree binaries from its source tree. As part of the
Kconfig conversion, the Makefiles were updated to align with how this
is done in Linux: a single target for each SoC is used to build all the
.dtb files for that SoC.

Since then, the Makefiles have devolved in some cases, resulting in
lots of target-specific build rules. Also Linux has moved to using
subdirectories for each vendor.

Recent work aims to allow U-Boot to directly use devicetree files from
Linux. This would be easier if the directory structure were the same.
Another recent discussion involved dropping the build rules altogether.

This series makes a start at cleaning up some of the build rules, to
reduce the amount of code and make it easier to add new boards for the
same SoC.

One issue is that the ARCH_xxx Kconfig options between U-Boot and Linux
are not always the same. Given the large number of SoCs and boards
supported by U-Boot, it would be useful to align these where possible.
