Boot failure on u740

Hi all,

I am trying to boot android kernel on u740 using yocto. The android kernel version is 5.10.43.
In yocto sources tag 2021.02, I replaced kernel 5.10.17 with android kernel version 5.10.43.
Also removed patches
0020-riscv-Introduce-alternative-mechanism-to-apply-errat.patch
0021-riscv-sifive-apply-errata-cip-453-patch.patch.

And build the unmatched image.

Following is the error I am facing:
U-Boot SPL 2021.01 (Sep 16 2021 - 06:46:05 +0000)
Trying to boot from MMC1
Unhandled exception: Load access fault

U-boot doesn’t even get to loading the kernel, let alone running it. It looks like it crashes while loading the second stage (ITB) from MMC. Mind that u-boot needs patches too, the upstream version doesn’t work correctly on the Unmatched yet.
