I’ve been looking into this.  As of u-boot v2019.10, there are some extra checks in efi_disk_read_blocks() and now it will fail with EFI_INVALID_PARAMETER if the buffer isn’t aligned.  In my case, efi_disk_read_blocks() was called with a buffer address of 0x1da06040 but with this->media->io_align = 512.  (See lib/efi_loader/efi_disk.c line 125.). Evidently,loader.efi is making disk calls with unaligned buffers but it wasn’t an issue until these checks were added.  That’s as far as I got debugging this.
