Subject: [PATCH] Set a devicetree var in a BLS config if GRUB_DEFAULT_DTB is
present
The BootLoaderSpec mentions that a devicetree field can be used to pass a
Device Tree (DT) to the kernel, for the platforms that use it to describe
information about the hardware.
The blscfg module supports parsing the field from the BLS snippets but it
allows to set a DT for all the entries if a devicetree env var is defined.
Make the grub2-mkconfig tool to set this variable if GRUB_DEFAULT_DTB was
defined in the /etc/default/grub file.
