Subject: [PATCH] arm64: make sure fdt has #address-cells and #size-cells
|
|
|
8631a2 |
properties
|
|
|
8631a2 |
|
|
|

Recent upstream changes to kexec-tools relies on #address-cells
|
|
|
8631a2 |
and #size-cells properties in the FDT. If grub2 needs to create
|
|
|
8631a2 |
a chosen node, it is likely because firmware did not provide one.
|
|
|
8631a2 |
In that case, set #address-cells and #size-cells properties to
|
|
|
8631a2 |
make sure they exist.
