Subject: [PATCH] ARM64: dts: bcm: Use a symlink to R-Pi dtsi files from arch=arm
The ../../../arm... style cross-references added by commit 9d56c22a7861
("ARM: bcm2835: Add devicetree for the Raspberry Pi 3.") do not work in the
context of the split device-tree repository[0] (where the directory
structure differs). As with commit 8ee57b8182c4 ("ARM64: dts: vexpress: Use
a symlink to vexpress-v2m-rs1.dtsi from arch=arm") use symlinks instead.
These includes in turn require a skeleton.dtsi to be present, so add one as
a real file (with the same contents as arch/arm) rather than a symlink.
