Adding your patch on top of Julien Grall's patch appears to push the Xen
boot of my target device (Raspberry PI 4B with Tianocore) further.  Still
yet to see any output attributable to the Domain 0 kernel though.

(XEN) *** LOADING DOMAIN 0 ***
(XEN) Loading d0 kernel from boot module @ 0000000032234000
(XEN) Loading ramdisk from boot module @ 0000000031747000
(XEN) Allocating 1:1 mappings totalling 2048MB for dom0:

(XEN) BANK[1] 0x00000040000000-0x000000b0000000 (1792MB)
(XEN) Grant table range: 0x000000315f3000-0x00000031633000

The line, "Loading d0 DTB to 0x0000000028000000-0x0000000028000273" seems
rather suspicious as I would expect Domain 0 to see ACPI tables, not a
device tree.

Your (Masami Hiramatsu) patch seems plausible, but things haven't
progressed enough for me to endorse it.  Looks like something closer to
the core of ACPI still needs further work, Julien Grall?
