As described in the Xen PVH documentation [1], "ebx: contains the physical memory address where the loader has placed the boot start info structure". To have this pointer saved to be able to use it later in the PEI phase, we allocate some space in the MEMFD for it. We use 'XPVH' as a signature (for "Xen PVH").
