Subject: [PATCH v2 1/5] ArmPlatformPkg/NorFlashDxe: prepare for devicepath format change
Date: Wed, 21 Nov 2018 12:58:24 +0100 [thread overview]
Message-ID: <20181121115828.3026-2-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20181121115828.3026-1-ard.biesheuvel@linaro.org>
A subsequent patch will change the layout of devicepath nodes
produced by this driver. In preparation, make some tweaks to
the code to use a packed struct for the devicepath and to pass
the device index to NorFlashCreateInstance(). These are cosmetic
changes only, the resulting binaries should be identical.
