cfb4aa2a75 efi_loader: Avoid mapping the ACPI tables twice
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:

53d5a22163 emulation: Use bloblist to hold tables
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.

9c5399a73d verdin-am62: fix FASTBOOT_BUF_ADDR and FASTBOOT_BUF_SIZE
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.
