This function is somewhat ambiguous, so expand the comments and add a

Add bloblist support so that tables can be generated and placed in a

The add_u_boot_and_runtime() function paints with a broad brush,
considering all of the memory from the top of U-Boot stack to
gd->ram_top as EFI_RUNTIME_SERVICES_CODE
This is fine, but we need to make sure we don't add a separate entry for
any ACPI tables in this region (which happens when bloblist is used for
tables). Otherwise the memory map looks strange and we get a test
failure on qemu-x86 (only) for the 'virtual address map' test.
Good map:

This isn't strictly needed, but with UPL we use the reserved-memory
nodes to indicate where the SMBIOS table is. Tianocore requires 4KB
alignment on these regions, so it is easier to adjust the alignment
to match.

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 provides the tables in a mapped memory region and U-Boot
makes use of these directly, 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.

The current value of CONFIG_FASTBOOT_BUF_ADDR is incorrect for hardware
with 512MB and 1GB of RAM. The RAM address ranges for these devices are:
- 512MB:
- Start: 0x80000000
- End: 0xA0000000
- 1GB:
- Start: 0x80000000
- End: 0xC0000000
The current buffer address makes fastboot downloads work only on
hardware with 2GB of RAM.
To fix this issue:
1. Lower CONFIG_FASTBOOT_BUF_ADDR to 0x88200000. This makes the buffer
to be equal ot CONFIG_SYS_LOAD_ADDR, which is a safe address to
download files using fastboot.
2. Reduce the size of the download buffer to 128MB, avoiding overlaps
with RAMDISK_ADDR_R. This is a good enough value for individual
downloads.
These changes make fastboot downloads work with 512MB and 1GB devices.
