This might actually not a "crash". Instead, it seems the boot address for
CPUs 1-7 hasn't been set correctly, causing them to boot from the BootROM.

I believe this is not a U-Boot issue, but rather an OpenSBI one. According
to the log, it looks like you are using mainline OpenSBI. Could you please
confirm the OpenSBI you are using includes this fix:

126c9d34 ("platform: generic: spacemit: add missing objects.mk")
