Subject: [PATCH 3/3] ARM/arm64: efistub: perform hardware compatibility check
Date: Thu, 28 Jan 2016 18:02:29 +0100 [thread overview]
Message-ID: <1454000549-9189-4-git-send-email-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <1454000549-9189-1-git-send-email-ard.biesheuvel@linaro.org>
Before proceeding with relocating the kernel and parsing the command line,
insert a call to check_platform_features() to allow an arch specific check
to be performed whether the current kernel can execute on the current
hardware.
