Subject: [PATCH v2 2/9] ArmPlatformPkg/ArmVExpressDxe: remove ARM support
Date: Fri, 31 Mar 2017 15:14:27 +0100	[thread overview]
Message-ID: <20170331141434.20810-3-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20170331141434.20810-1-ard.biesheuvel@linaro.org>

The 32-bit ARM support in this driver is unused, and thus untested.
So let's just remove it.
