maybe this is nicer?

mt7986a-bananapi-bpi-r3-emmc-nand-dtbs := mt7986a-bananapi-bpi-r3.dtb \
					  mt7986a-bananapi-bpi-r3-emmc.dtbo \
					  mt7986a-bananapi-bpi-r3-nand.dtbo
dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3-emmc-nand.dtb
mt7986a-bananapi-bpi-r3-emmc-nor-dtbs := mt7986a-bananapi-bpi-r3.dtb \
					 mt7986a-bananapi-bpi-r3-emmc.dtbo \
					 mt7986a-bananapi-bpi-r3-nor.dtbo
dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3-emmc-nor.dtb
mt7986a-bananapi-bpi-r3-sd-nand-dtbs := mt7986a-bananapi-bpi-r3.dtb \
					mt7986a-bananapi-bpi-r3-sd.dtbo \
					mt7986a-bananapi-bpi-r3-nand.dtbo
dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3-sd-nand.dtb
mt7986a-bananapi-bpi-r3-sd-nor-dtbs := mt7986a-bananapi-bpi-r3.dtb \
				       mt7986a-bananapi-bpi-r3-sd.dtbo \
				       mt7986a-bananapi-bpi-r3-nor.dtbo
dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3-sd-nor.dtb

here i tried to align the text on first name, but this results in visible stairs.
maybe only 1 tab to indent here (or anything else)? what do you think? In the end
better readable as 1 long line.

the SATA-Patch [1] will then add a line to each of the 4 blocks here (+5 lines in total except changes by adding the backslash).
