Subject: [PATCH 3/4] SecurityPkg: remove PE/COFF header workaround for ELILO on IPF
Date: Thu, 6 Sep 2018 15:45:22 +0200 [thread overview]
Message-ID: <20180906134523.2036-4-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20180906134523.2036-1-ard.biesheuvel@linaro.org>
Now that Itanium support has been dropped, we can remove the various
occurrences of the ELILO on Itanium PE/COFF header workaround.
