Subject: [PATCH 038/176] arm64/xen_boot: Fix Xen boot using GRUB2 on AARCH64
|
|
|
bc092b9 |
|
|
|
bc092b9 |
Xen is currently crashing because of malformed compatible property for
|
|
|
bc092b9 |
the boot module. This is because the property string is not
|
|
|
bc092b9 |
null-terminated as requested by the ePAR spec.
