Subject: [PATCH 20/37] xen: introduce CONFIG_EFI to stub API for non-EFI architecture
Date: Thu, 23 Sep 2021 20:02:19 +0800 [thread overview]
Message-ID: <20210923120236.3692135-21-wei.chen@arm.com> (raw)
In-Reply-To: <20210923120236.3692135-1-wei.chen@arm.com>
Some architectures do not support EFI, but EFI API will be used
in some common features. Instead of spreading #ifdef ARCH, we
introduce this Kconfig option to give Xen the ability of stubing
EFI API for non-EFI supported architectures.
