+Subject: [PATCH] plat: mediatek: mt8195: use libdram to pass actual memory
+ size to U-Boot
+
+Since libdram can obtain the actual memory size at runtime, make it possible
+to pass this value to U-Boot. This allows the bootloader to adapt to boards
+with different DRAM sizes without requiring manual configuration.
+All credit to Bartosz Bilas' work for the mt8188.
