Hello Simon,
Useful rules in scripts/Makefile.lib allows us to easily generate a device tree blob and wrap it in assembly code.
We do not need to parse a linker script to get output format and arch.
This commit deletes ./u-boot.dtb since it is a copy of dts/dt.dtb
I'd rather have the former and delete the latter temporary file as part of the build. u-boot.dtb is currently a build output.
This is what I have said in the thread Re: [PATCH] dts: re-write dts/Makefile more simply with Kbuild
We must keep dts/dt.dtb to suppress the re-generation of dts/dt.dtb.
OK. From memory when I did this, it was just a temporary file which was used to create dts/dt.o. Make deleted it at the end of the build, I think. But I may remember wrong, and it doesn't matter anyway.
Besides, dts/dt.dtb is a prerequisite of dts/dt.dtb.S when CONFIG_OF_EMBED is enabled.
I believe keeping dts/dt.dtb is reasonable enough.
Better to keep both?
Yes I think so.
Regards, Simon
