Subject: [PATCH v5 1/8] x86/platform/uv: Add platform resolving #defines for misc GAM_MMIOH_REDIRECT*
Date:   Tue,  4 Apr 2023 16:14:24 -0500
Message-Id: <20230404211431.776248-2-steve.wahl@hpe.com>
In-Reply-To: <20230404211431.776248-1-steve.wahl@hpe.com>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Upcoming changes will require use of new #defines
UVH_RH_GAM_MMIOH_REDIRECT_CONFIG0_NASID_MASK and
UVH_RH_GAM_MMIOH_REDIRECT_CONFIG1_NASID_MASK, which provide the
appropriate values on different uv platforms.

Also, fix typo that defined a couple of "*_CONFIG0_*" values twice
where "*_CONFIG1_*" was intended.
