Subject: [PATCH 08/14] arm: efi: remove forbidden values from the PE/COFF header
Date: Fri, 18 Aug 2017 20:49:41 +0100	[thread overview]
Message-ID: <20170818194947.19347-9-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20170818194947.19347-1-ard.biesheuvel-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>

Bring the PE/COFF header in line with the PE/COFF spec, by setting
NumberOfSymbols to 0, and removing the section alignment flags.
