efi_loader: add SMBIOS table measurement

2021-10-26T15:58:14Z

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; Signed-off-by: Masahisa Kojima

smbios: error handling for invalid addresses

2021-07-24T08:49:51Z

SMBIOS tables only support 32bit addresses. If we don't have memory here handle the error gracefully: * on x86_64 fail to start U-Boot * during UEFI booting ignore the missing table Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

smbios: Fix BIOS Characteristics Extension Byte 2

We currently define the EFI support of an SMBIOS table as the third bit of "BIOS Characteristics Extension Byte 1". The latest DMTF spec defines it on "BIOS Characteristics Extension Byte 2". Signed-off-by: Ilias Apalodimas Remove superfluous assignment. Signed-off-by: Heinrich Schuchardt

smbios: Allow writing to the coreboot version string

2021-03-27T00:59:37Z

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. Signed-off-by: Simon Glass

smbios: Add more options for the BIOS version string

2021-02-06T11:20:27Z

At present the version string is obtained from PLAIN_VERSION. Some boards may want to configure this using the device tree, since the build system can more easily insert things there after U-Boot itself is built. Add this option to the code. Also in some cases the version needs to be generated programmatically, such as when it is stored elsewhere in the ROM and must be read first. To handle this, keep a pointer around so that it can be updated later. This works by storing the last string in the context, since it is easier than passing out a little-used extra parameter. Provide a function to update the version string. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

smbios: Use char consistently for the eos member

At present a few of the structs use u8 instead of char. This is a string, so char is better. Update them. Signed-off-by: Simon Glass Reviewed-by: Christian Gmeiner Reviewed-by: Bin Meng

smbios: Move smbios_write_type to the C file
