The J721E SR2.0 silicon revision requires an OTAP delay of 0x8[0] for eMMC HS200 mode instead of the 0x6 default used by earlier revisions. Hence, detect the SoC revision at runtime and patch the devicetree accordingly. Why are you adding this to SoC board file instead of the MMC driver? We support DT tap delay property parsing, compatible parsing, and silicon revision parsing in both u-boot and Linux drivers, so this should live in the driver instead of the SoC board file. ~ Judith ....
