+Something between U-Boot 2023.04 and 2023.07.02 resulted in no longer
+implicitely including <linux/sizes.h> in the DDR3 RAM driver for the
+MT7929 SoC. The result is a build failure:
+drivers/ram/mediatek/ddr3-mt7629.c: In function 'mtk_ddr3_get_info':

+Include <linux/sizes.h> so SZ_* is defined.
