+Date: Mon, 10 Aug 2026 15:40:06 +0100
+Subject: [PATCH] DynamicTablesPkg: fix SmbiosType2Genertor build failure with
+ clang
+
+BaseboardCount type is UINT32. Using MAX_UINTN in the comparision
+triggers below build error:
+
+  type 'UINT32' (aka 'unsigned int') is always false
+    [-Werror,-Wtautological-constant-out-of-range-compare]
+  199 |       (BaseboardCount > (MAX_UINTN / sizeof (*CmObjectList))))
+
+To address this, use MAX_UINT32 instead of MAX_UINTN.
