When CONFIG_SPL_MULTI_DTB_FIT is enabled, multiple device trees are

and the FIT image start address are 8-byte aligned, the DTBs embedded
within the FIT image are not guaranteed to maintain 8-byte alignment.
Because DT properties are 4-byte aligned, and fitImage is a DT with long
binary strings encoded in them. But that is not the case here, because
the invocation does use mkimage -E .
Therefore I see two issues:
- Should the code which handles LEGACY fitImages with 4-byte alignment
be fixed to relocate the blobs ? I think yes.
- Should mkimage -E align blobs to 8 bytes by default ? I think yes, and
frankly, I thought it does so already, but apparently not.
