QEMU can have its own internal ACPI and SMBIOS tables. At present U-Boot copies out the SMBIOS tables but points directly to the ACPI ones.
The ACPI tables are not aligned on a 4KB boundary, which means that UPL cannot use them directly, since it uses a reserved-memory node for the tables and that it assumed (by EDK2) to be 4KB-aligned.
On x86, QEMU completely takes over the generation of these tables, thus making it difficult to use any common code.
Adjust the logic to fit within the existing table-generation code. Use a bloblist always and ensure that the ACPI tables is placed in an aligned region. Set a size of 8K for QEMU. This does not actually put all the tables in one place, for QEMU, since it currently adds a pointer to the tables in QFW.
On ARM, enable bloblist so that SMBIOS tables can be added to the bloblist.

Commits that are "big external project is doing things wrong, we need to work around it" are at best worrisome to me. If re-thinking what you're doing here isn't right, re-wording what you're doing to not be negative about other projects is what's needed then.
