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.
|
||
|
|
|
