* [Buildroot] [PATCH 1/1] board/zynqmp/post-image.sh: Don't insist on a xilinx/ prefix for .dts files.

If using BR2_LINUX_KERNEL_CUSTOM_DTS_PATH to copy .dts files from
buildroot into the linux tree, these .dts files are copied to
arch/arm64/boot. Unfortunately, the post-image.sh script expects to find
them in arch/arm64/boot/xilinx.

This patch does not require the xilinx/ prefix to be present when
symlinking the device-tree to system.dtb where u-boot expects to find
it.

I think the following simpler change would also work. Can you check
that please?

-               -e 's|^BR2_LINUX_KERNEL_INTREE_DTS_NAME="xilinx/([-_/[:alnum:]\\.]*).*"$|\1|p' \
+               -e 's|^BR2_LINUX_KERNEL_INTREE_DTS_NAME="([-_/[:alnum:]\\.]*).*"$|\2|p' \

Assuming you intended \1, not \2 here - this suggestion breaks behaviour for a couple of defconfigs in the tree. If I run the ZCU106 defconfig through this regexp, I get:

	$ cat configs/zynqmp_zcu106_defconfig | sed -nr -e 's|^BR2_LINUX_KERNEL_INTREE_DTS_NAME="([-_/[:alnum:]\\.]*).*"$|\1|p'
	xilinx/zynqmp-zcu106-revA

...this creates a dangling symlink in output/images (system.dtb -> xilinx/zynqmp-zcu106-revA.dtb).

The right behaviour is to strip any prefixes that exist, without requiring any. Something like:

-               -e 's|^BR2_LINUX_KERNEL_INTREE_DTS_NAME="xilinx/([-_/[:alnum:]\\.]*).*"$|\1|p' \
+               -e 's|^BR2_LINUX_KERNEL_INTREE_DTS_NAME="(.*/)?([-_/[:alnum:]\\.]*).*"$|\2|p' \

This is less Xilinx-specific, although it seems a tad greedy.

best,
Graeme

Yes, better keeping the xilinx prefix as this is a xilinx-specific
script anyway.
