[SeaBIOS] [PATCH RFC 0/3] qemu/acpi-build: cross migration fixes

[Michael S. Tsirkin]

This patchset, on top of my acpi branch,
fixes the issues with cross-version migration:
- Don't add fw cfg entries when running with -M 1.5 and older
- Future proof against future ACPI table changes:
  create a ROM blob so the tables are migrated
  (together with BIOS)

With these changes the ACPI generation patchset
will become mergeable.

I say *will* since it's only lightly tested,
I intend to test properly and re-post the full patchset
with acpi table geneation in QEMU ready for merge, next week.

Posting for early flames/review.

Michael S. Tsirkin (3):
  loader: support for unmapped ROM blobs
  acpi: add tables as ROM so they are migrated
  acpi-build: disable acpi generation for compat
