[PATCH 7/7] efi: Print the secure boot status in x86 setup_arch() [ver #7]

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Print the secure boot status in the x86 setup_arch() but otherwise do
nothing more for now.  More functionality will be added later, but this at
least allows for testing.
