Lost MTD drivers in kernel 5.10 branch

[Jupiter]

Hello,

I could run MTD and UBIFS very well in kernel 4.19 built by Yocto Zeus
branch, after upgrading to kernel 5.10 branch, I could not run MTD and
UBIFS, missing /dev/mtd* drivers and an empty table by cat /proc/mtd.

Given I set the identical MTD and UBI configuration in defconfig and
uboot configure for both kernels, I could not see defconf is causing
the MTD drivers problem in kernel 5.10 branch. Further adding the
debug on

The nand_base.c nand_detect was not called so all of following nand
functions were missing in kernel boot:

Are there any changes in kernel 5.10 MTD to require some new MTD configurations?

Appreciate your insider advice.

Thank you.
