Hi all,
As part of the unified features in u-boot thread I said that I would work to get distros to agree to a common location that u-boot will be able to assume exists for it to transparently load dtbs from for us.
I would like to propose /boot/dtb/
I think it needs to be in /boot/ to allow for booting from systems with / and /boot on separate partitions. I believe Ubuntu and hence Debian put them in /lib somewhere today. Fedora puts them in /boot/dtb-<kernel version>. im not sure where the other distros put them.
A DTB should not be tied to a kernel version. I realize that is a reality for some boards, but lets not encourage that. There are also plans to remove dts files from the kernel.
I think that until they are decoupled from the kernel Fedora would have /boot/dtb be a symlink to the latest installed kernel. once its decoupled it would be the location where the dtbs are installed.
If /boot/dtb is THE dtb to use, does more than that need to be specified (at least from a bootloader perspective).
Can We all agree to implement ensuing that dtb files will be available in /boot/dtb/
Are you aware of dtb support in syslinux menu files? This could be added to u-boot as well.
