0d73394ad9 SMBIOS: Fix type 17 field sizes
Fields for configured_clock_speed and various voltage values
introduced in spec v2.7+ should be "word", i.e. 16 bits.

84351843eb SMBIOS: Update Type 0 struct generator for machines >= 2.1
Update how type 0 (bios info) structures are generated, as follows:

  - convert bios_characteristics field to uin64_t (instead of
    uint8_t[8]), as described in the current smbios spec (v2.8)

  - enable "virtual machine" bit in bios_characteristics_extension_bits

  - add command line option to enable "uefi supported" bit in
    bios_characteristics_extension_bits

These updates should make this optional structure more useful when
used with edk2/ovmf. Only pc machines >= 2.1 are affected, and only
when a type 0 structure is explicitly specified on the command line.

c97294ec1b SMBIOS: Build aggregate smbios tables and entry point
Build an aggregate set of smbios tables and an entry point structure.

Insert tables and entry point into fw_cfg respectively under
"etc/smbios/smbios-tables" and "etc/smbios/smbios-anchor".

Machine types <= 2.0 will for now continue using field-by-field
overrides to SeaBIOS defaults, but for machine types 2.1 and up we
expect the BIOS to look for and use the aggregate tables generated
by this patch.

2e6e8d7a25 SMBIOS: Use bitmaps to prevent incompatible comand line options
Replace existing smbios_check_collision() functionality with
a pair of bitmaps: have_binfile_bitmap and have_fields_bitmap.
Bits corresponding to each smbios type are set by smbios_entry_add(),
which also uses the bitmaps to ensure that binary blobs and field
values are never accepted for the same type.

These bitmaps will also be used in the future to decide whether
or not to build a full table for a given smbios type.

e41fca3da7 SMBIOS: Update header file definitions
Add definitions for smbios entry point (anchor), and for type 2
(base board) structure which is required by some versions of OS X.

Remove definition for type 20 (memory device mapped address)
structure, which is no longer required as of smbios spec v2.5.

Update all other structure definitions to bring them into
compliance with smbios spec v2.8.

This patch contains no functional changes.

Rename the following symbols:

  - smbios_set_type1_defaults() to the more general smbios_set_defaults();
  - bool smbios_type1_defaults to the more general smbios_defaults;
  - smbios_get_table() to smbios_get_table_legacy();

b29ad07ee8 smbios: Set system manufacturer, product & version by default
Currently, we get SeaBIOS defaults: manufacturer Bochs, product Bochs,
no version.  Best SeaBIOS can do, but we can provide better defaults:
manufacturer QEMU, product & version taken from QEMUMachine desc and
name.

Take care to do this only for new machine types, of course.

Note: Michael Tsirkin doesn't trust us to keep values of QEMUMachine member
product stable in the future.  Use copies instead, and in a way that
makes it obvious that they're guest ABI.

Note that we can be trusted to keep values of member name, because
that has always been ABI.

fc3b32958a smbios: Make multiple -smbios type= accumulate sanely
Currently, -smbios type=T,NAME=VAL,... adds one field (T,NAME) with
value VAL to fw_cfg for each unique NAME.  If NAME occurs multiple
times, the last one's VAL is used (before the QemuOpts conversion, the
first one was used).

Multiple -smbios can add multiple fields with the same (T, NAME).
SeaBIOS reads all of them from fw_cfg, but uses only the first field
(T, NAME).  The others are ignored.

"First one wins, subsequent ones get ignored silently" isn't nice.  We
commonly let the last option win.  Useful, because it lets you
-readconfig first, then selectively override with command line
options.

Clean up -smbios to work the common way.  Accumulate the settings,
with later ones overwriting earlier ones.  Put the result into fw_cfg
(no more useless duplicates).

Bonus cleanup: qemu_uuid_parse() no longer sets SMBIOS system uuid by
side effect.

0d09e41a51 hw: move headers to include/
Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.
