smbios: correctly name Structure Table Maximum Size field

2024-02-02T18:57:45+00:00

In the SMBIOS 3 entry point the Structure Table Maximum Size field was
incorrectly named max_struct_size. A Maximum Structure Size field only
exists in the SMBIOS 2.1 entry point and has a different meaning.

Call the Structure Table Length field table_maximum_size.

As a matter of programming style use logical or to combine two boolean

efi_loader: migrate SMBIOS 3.0 entry point structure for measurement

2024-01-26T13:16:17+00:00

Current U-Boot only supports the SMBIOS 3.0 entry point structure.
TCG2 measurement code should migrate to SMBIOS 3.0 entry
point structure.

efi_selftest tcg2 test also needs to be updated, and expected
PCR[1] result is changed since guid for SMBIOS EFI system table
uses different guid SMBIOS3_TABLE_GUID instead of SMBIOS_TABLE_GUID.

lib: smbios: remove redundant next_header()

2024-01-16T22:05:29+00:00

next_header() and get_next_header() only differ in how the const attribute
is used. One function taking a const parameter and returning a non-const is
good enough.

smbios: smbios.h should not import ofnode.h

2024-01-09T09:09:15+00:00

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.

lib: smbios: verify_checksum() is duplicate

2024-01-09T09:09:09+00:00

The function verify_checksum() duplicates what table_compute_checksum()
does. Replace it. table_compute_checksum() is always compiled.

lib: Remove inclusion from these files

2023-12-21T13:54:37+00:00

After some header file cleanups to add missing include files, remove
common.h from all files in the lib directory. This primarily means just
dropping the line but in a few cases we need to add in other header
files now.

efi_loader: add SMBIOS table measurement

2021-10-26T15:58:14+00:00

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;

smbios: Allow writing to the coreboot version string

2021-03-27T00:59:37+00:00

When U-Boot is booted from coreboot the SMBIOS tables are written by
coreboot, not U-Boot. The existing method of updating the BIOS version
string does not work in that case, since gd->smbios_version is only set
when U-Boot writes the tables.

Add a new function which allows the version to be updated by parsing the
tables and writing the string in the correct place. Since coreboot
provides a pointer to the SMBIOS tables in its sysinfo structure, this
makes it easy to do the update.
