Subject: [PATCH v3 05/16] MdePkg/ProcessorBind.h AARCH64: limit MAX_ADDRESS to 48 bits
Date: Wed, 28 Nov 2018 15:33:46 +0100 [thread overview]
Message-ID: <20181128143357.991-6-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20181128143357.991-1-ard.biesheuvel@linaro.org>
AArch64 supports the use of more than 48 bits for physical and/or
virtual addressing, but only if the page size is set to 64 KB,
which is not supported by UEFI. So redefine MAX_ADDRESS to cover
only 48 address bits.
