lib/Kconfig: Correct typo about SYSINFO_SMBIOS in help message

2023-12-13T14:57:02Z

The correct symbol to enable to have SMBIOS populate fields based on the device tree is SYSINFO_SMBIOS and not SMBIOS_SYSINFO. Signed-off-by: Tom Rini Reviewed-by: Simon Glass

bootX measurements and measurement API moved to u-boot core: Up to now, U-Boot could perform measurements and EventLog creation as described by the TCG spec when booting via EFI. The EFI code was residing in lib/efi_loader/efi_tcg2.c and contained both EFI specific code + the API needed to access the TPM, extend PCRs and create an EventLog. The non-EFI part proved modular enough and moving it around to the TPM subsystem was straightforward. With that in place we can have a common API for measuring binaries regardless of the boot command, EFI or boot(m|i|z), and contructing an EventLog. I've tested all of the EFI cases -- booting with an empty EventLog and booting with a previous stage loader providing one and found no regressions. Eddie tested the bootX part. Eddie also fixed the sandbox TPM which couldn't be used for the EFI code and it now supports all the required capabilities. This had a slight sideeffect in our testing since the EFI subsystem initializes the TPM early and 'tpm2 init' failed during some python tests. That code only opens the device though, so we can replace it with 'tpm2 autostart' which doesn't error out and still allows you to perfom the rest of the tests but doesn't report an error if the device is already opened. There's a few minor issues with this PR as well but since testing and verifying the changes takes a considerable amount of time, I prefer merging it now. Heinrich has already sent a PR for -master containing "efi_loader: fix EFI_ENTRY point on get_active_pcr_banks" and I am not sure if that will cause any conflicts, but in any case they should be trivial to resolve. Both the EFI and non-EFI code have a Kconfig for measuring the loaded Device Tree. The reason this is optional is that we can't reason when/if devices add random info like kaslr-seed, mac addresses etc in the DT. In that case measurements are random, board specific and eventually useless. The reason it was difficult to fix it prior to this patchset is because the EFI subsystem and thus measurements was brought up late and DT fixups might have already been applied. With this patchset we can measure the DT really early in the future. Heinrich also pointed out that the two Kconfigs for the DTB measurements can be squashed in a single one and that the documentation only explains the non-EFI case. I agree on both but as I said this is a sane working version, so let's pull this first it's aleady big enough and painful to test.

tpm: Support boot measurements

2023-10-27T10:14:47Z

Add TPM2 functions to support boot measurement. This includes starting up the TPM, initializing/appending the event log, and measuring the U-Boot version. Much of the code was used in the EFI subsystem, so remove it there and use the common functions.

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. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

2023-09-21T22:05:40Z

When booted from coreboot, U-Boot does not build the SMBIOS tables, but it should still pass them on to the OS. Add a new option which indicates whether SMBIOS tables are present, however they were built. Flip the ordering so that the dependency is listed first, which is less confusing. Adjust GENERATE_SMBIOS_TABLE to depend on this new symbol. Signed-off-by: Simon Glass Reviewed-by: Heinrich Schuchardt Reviewed-by: Bin Meng
