I've checked the upper 16 MB - simply dumped the block at 0xff9f0000 (0xff000000 is the last 16 MB + MRC cache region offset 0x9f0000 from the layout file ) where in my image the MRC cache region resides (I can confirm it's there by dumping the image from flash). The data I read from the supposed memory mapping is all 0xff.
IIRC, you already confirmed with an external programmer that the data is written at this location, right? If the data is there but not memory mapped, maybe that offset isn't covered by the BIOS region in IFD?
fmd and .config files are attached
I didn't spot anything problematic there. But as you don't have CONFIG_VBOOT selected, you could also try a much simpler FMD file or just the automatically generated default, by unsetting CONFIG_FMDFILE.
