The ZSBL loads next stage (i.e. FSBL or U-Boot SPL) from a
partition with GUID type 2e54b353-1271-4842-806f-e436d6af6985
You need to document how U-Boot SPL will detect a partition
containtaining u-boot.itb image.
Don't augment this document instead simply update the contents
and various bootlogs assuming that everyone will use U-Boot SPL
+ FW_DYNAMIC + U-Boot combination. We don't want people to
stop using FW_PAYLOAD + U-Boot combination going forward.
After this series is merged, send a patch to OpenSBI as well to
update docs/platform/sifive_fu540.md

Anup
