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': drivers/ram/mediatek/ddr3-mt7629.c:734:30: error: 'SZ_128M' undeclared (first use in this function) 734 | info->size = SZ_128M; | ^~~~~~~ drivers/ram/mediatek/ddr3-mt7629.c:734:30: note: each undeclared identifier is reported only once for each function it appears in drivers/ram/mediatek/ddr3-mt7629.c:737:30: error: 'SZ_256M' undeclared (first use in this function) 737 | info->size = SZ_256M; | ^~~~~~~ drivers/ram/mediatek/ddr3-mt7629.c:740:30: error: 'SZ_512M' undeclared (first use in this function) 740 | info->size = SZ_512M; | ^~~~~~~ drivers/ram/mediatek/ddr3-mt7629.c:743:30: error: 'SZ_1G' undeclared (first use in this function) 743 | info->size = SZ_1G; | ^~~~~
Include <linux/sizes.h> so SZ_* is defined.
