Let me dig up the entire thread and have a look later. gmail
helped me out and tagged this entire series as spam .. so I
didn't see any of it.

OMAP5 uEVM and AM335x EVM. For these devices U-Boot does a simple extload from the /boot directory of the dtb. The goal here is to have the dtb name in /boot match the name that would be generated when you build the dtb in the kernel.
For example the omap5-uevm.dts file is compiled as omap5-uevm.dtb. So using a symlink with this standard naming makes it easier for u-boot to detect the device it is running on and look for the standard file name vs devicetree-uImage-omap5-evm.dtb.
Also, for people that want to load the dtb from other locations such as a different partition on the SD card they can still just copy the dtb file from the kernel build and not need to modify u-boot to use the different file name, just the location.

And what about the comments on your patch itself below?

I was trying to figure out the same thing when reviewing this
change this morning.
I'm not alternatives expert, but isn't DTB_NAME just the name
of the alternate being introduced ? If that's the case, why not
continue to use what the rest of the linux-dtb file uses ?
DTB_NAME=`echo ${KERNEL_IMAGE_BASE_NAME} | sed
"s/${MACHINE}/${DTS_BASE_NAME}/g"`
But outside of that (and Darren't already pending comments), the approach
looks fine and valid to me.
Cheers,
Bruce

From the do_install section the file I'm trying to symlink to is installed as
install -m 0644 ${DTS_BASE_NAME} ${D}/boot/devicetree-${DTB_SYMLINK_NAME}.dtb
So there isn't quite a variable that holds the proper value. However, I should be able to make this match more with the do_install section by using DTB_SYMLINK_NAME. I'll send a patch once I make the change and can test it.

Sorry, I didn't notice this comment before. I can reset this for tabs instead of space. I'll send a new version.
