I think remove it is not correct, the exact time should be measured using oscilloscope, removing it might make sd3.0 not work. But anyway 20000 seems too large a value.
Do you plan to submit a fix for this then? If you don't have the bandwidth for working on this, then we could go with my proposal.
I would like to be able to boot a kernel from the SD card in the 2021.04 release and fix the regression.
Also, why don't we have such property in the imx8mq-evk.dts in the kernel?
I don't think U-Boot dts should deviate from the Linux devicetree in this aspect.
See https://source.codeaurora.org/external/imx/linux-imx/tree/arch/arm64/boot/dt...
NXP vendor tree has off-on-delay-us.
