Hello,
I have a custom board based on AM335x and currently using 5.4 kernel. I am in processing of migrating from 5.4 to 5.10 kernel but 5.10 kernel seems to be unable to mount rootfs neither over NFS not from EMMC and it hangs there. Could anyone please help me on the issue resolution. Please find full logs below:

I compared eMMC related node from am33xx-l4.dtsi and I observed that driver is changed from ti,omap4-hsmmc to ti,am335-sdhci. Can this cause any issue? I am thinking if anything is wrong with eMMC then it should at-least boot over NFS which not happening either.
