1c5aab803c smbios: copy QEMU tables
QEMU provides SMBIOS tables with detailed information. We should not try to
replicate them in U-Boot.

If we want to inform about U-Boot, we can add a Firmware Inventory
Information (type 45) table in future.

efe441a0a3 smbios: smbios.h should not import ofnode.h
The smbios.h include does not use any definitions from ofnode.h.
So don't include it.

As DECLARE_GLOBAL_DATA_PTR is no longer defined via dm/of.h we need to
add it to efi_smbios.c.

Add now missing includes to smbios-parser.c.

Remove a superfluous check comparing the sizes of the SMBIOS 2.1 and SMBIOS
3.0 anchors.

06ef8089f8 efi: Correct smbios-table installation
At present this code allocates memory when writing the tables and
then unnecessarily adds another memory map when installing it.

Adjust the code to allocate the tables using the normal U-Boot
mechanism. This avoids doing an EFI memory allocation early in
U-Boot, which may use memory that would be overwritten by a
'load' command, for example.

138e69149b efi: Use the correct GUID for the SMBIOS table
EFI does not use the 'anchor string' to determine the SMBIOS table
version, instead preferring to have two separate GUIDs. Use the correct
one, depending on the table version.

Call unmap_system() to balance to the use of map_sysmem()

53fab13a7b efi: Use the installed SMBIOS tables
U-Boot should set up the SMBIOS tables during startup, as it does on x86.
Ensure that it does this correctly on non-x86 machines too, by creating
an event spy for last-stage init.

Tidy up the installation-condition code while we are here.

3d49ee8510 efi_loader: add SMBIOS table measurement
TCG PC Client Platform Firmware Profile Specification
requires to measure the SMBIOS table that contains static
configuration information (e.g. Platform Manufacturer
Enterprise Number assigned by IANA, platform model number,
Vendor and Device IDs for each SMBIOS table).

The device- and environment-dependent information such as
serial number is cleared to zero or space character for
the measurement.

Existing smbios_string() function returns pointer to the string
with const qualifier, but exisintg use case is updating version
string and const qualifier must be removed.
This commit removes const qualifier from smbios_string()
return value and reuses to clear the strings for the measurement.

This commit also fixes the following compiler warning:

lib/smbios-parser.c:59:39: warning: cast to pointer from integer of
different size [-Wint-to-pointer-cast]
  const struct smbios_header *header = (struct smbios_header *)entry->struct_table_address;

dee37fc99d Remove <inttypes.h> includes and PRI* usages in printf() entirely
In int-ll64.h, we always use the following typedefs:

  typedef unsigned int         u32;
  typedef unsigned long        uintptr_t;
  typedef unsigned long long   u64;

This does not need to match to the compiler's <inttypes.h>.
Do not include it.

The use of PRI* makes the code super-ugly.  You can simply use
"l" for printing uintptr_t, "ll" for u64, and no modifier for u32.

62f3757870 efi_loader: Allow SMBIOS tables in highmem
We try hard to make sure that SMBIOS tables live in the lower 32bit.
However, when we can not find any space at all there, we should not
error out but instead just fall back to map them in the full address
space instead.

This can for example happen on systems that do not have any RAM mapped
in the lower 32bits of address space. In that case having any SMBIOS
tables at all is better than having none.
