Subject: [PATCH 2/6] arm/efi: Allow invocation of arbitrary runtime services
Date: Tue, 22 Nov 2016 00:31:46 +0000 [thread overview]
Message-ID: <147977470660.6360.5713293266942511695.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <20161117123731.GA11573@wunner.de>
Provide the ability to perform mixed-mode runtime service calls for arm in
the same way that commit 0a637ee61247bd4bed9b2a07568ef7a1cfc76187 provides
the ability to invoke arbitrary boot services.
