efi: Conflict efi_loader with different stub bitness We have 2 users of the EFI headers: efi_loader and the EFI stub. Efi_loader always expects that the bitness of the definitions it uses is identical to the execution. The EFI stub however allows to run x86_64 U-Boot on 32bit EFI and the other way around, so it allows for different bitness of EFI definitions and U-Boot environment. This patch explicitly requests via Kconfig that efi_loader can only be enabled if the bitness is identical. Because we can run efi_loader on x86_64 without EFI stub enabled, it also ensures that this case propagates the correct ABI constraints. Signed-off-by: Alexander Graf <agraf@suse.de>

efi_loader: Introduce eventlog support for TCG2_PROTOCOL In the previous patches we only introduced a minimal subset of the EFI_TCG2_PROTOCOL protocol implementing GetCapability(). So let's continue adding features to it, introducing the GetEventLog() and HashLogExtendEvent() functions. In order to do that we first need to construct the eventlog in memory, specifically in EFI_BOOT_SERVICES_DATA memory and a configuration table from EFI_ACPI_MEMORY_NVS. U-Boot won't currently add any events to the log or measure any components, but will expose the necessary EFI APIs for applications to do so.

efi_loader: Implement FileLoad2 for initramfs loading Following kernel's proposal for an arch-agnostic initrd loading mechanism [1] let's implement the U-boot counterpart. This new approach has a number of advantages compared to what we did up to now. The file is loaded into memory only when requested limiting the area of TOCTOU attacks. Users will be allowed to place the initramfs file on any u-boot accessible partition instead of just the ESP one. Finally this is an attempt of a generic interface across architectures in the linux kernel so it makes sense to support that. The file location is intentionally only supported as a config option argument(CONFIG_EFI_INITRD_FILESPEC), in an effort to enhance security. Although U-boot is not responsible for verifying the integrity of the initramfs, we can enhance the offered security by only accepting a built-in option, which will be naturally verified by UEFI Secure Boot. This can easily change in the future if needed and configure that via ENV or UEFI variable.

efi_loader: signature: rework for intermediate certificates support In this commit, efi_signature_verify(with_sigdb) will be re-implemented using pcks7_verify_one() in order to support certificates chain, where the signer's certificate will be signed by an intermediate CA (certificate authority) and the latter's certificate will also be signed by another CA and so on. What we need to do here is to search for certificates in a signature, build up a chain of certificates and verify one by one. pkcs7_verify_one() handles most of these steps except the last one. pkcs7_verify_one() returns, if succeeded, the last certificate to verify, which can be either a self-signed one or one that should be signed by one of certificates in "db". Re-worked efi_signature_verify() will take care of this step. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org>
