Subject: [RFC PATCH 5/7] ArmPlatformPkg/MemoryInitPeim: take MAX_ALLOC_ADDRESS into account
Date: Fri, 7 Dec 2018 12:23:02 +0100 [thread overview]
Message-ID: <20181207112304.19765-6-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20181207112304.19765-1-ard.biesheuvel@linaro.org>
Limit the PEI memory region so it will not extend beyond what we can
address architecturally when running with 4 KB pages.
Contributed-under: TianoCore Contribution Agreement 1.1
