Subject: [PATCH v2 04/13] ArmPkg/CpuPei: base GCD memory space size on CPU's PA range
Date: Mon, 26 Nov 2018 23:37:52 +0100 [thread overview]
Message-ID: <20181126223801.17121-5-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20181126223801.17121-1-ard.biesheuvel@linaro.org>
Derive the size of the GCD memory space map directly from the CPU's
information registers rather than from the PcdPrePiCpuMemorySize PCD,
which will be removed.
