When the malloc() region extends beyond 4GB on ARM we may end up with
an SMBIOS table in that region.

Add support for writing an SMBIOS3 table, which supports a 64-bit
address.

Note that this problem does not happen on x86 since it requires the
tables to be placed just below 1MB in memory, unless
CONFIG_BLOBLIST_TABLES is enabled.


Changes in v2:
- Check the end of the table rather than the start.
- Add a new patch to correct gd_smbios_start()
- Add a note about why unmap_system() is called

Simon Glass (6):
  smbios: Refactor 32-bit code into an else statement
  smbios: Move the rest of the SMBIOS2 code
  smbios: Use SMBIOS 3.0 to support an address above 4GB
  smbios: Correct gd_smbios_start()
  efi: Use the correct GUID for the SMBIOS table
  smbios: Require the caller to align the SMBIOS table
