4386b0b0439c1115a45d006b3c0b47b34c45ce0e tcgbios: Implement tpm_hash_log_extend_event_buffer
Implement tpm_hash_log_extend_event_buffer() that allows to measure
the contents of a buffer into a given PCR and log it with the
given event type and description. The caller may choose to have
the size of an ELF image file detected so that only data from the
ELF image are hashed rather than the much larger buffer.
Besides using this function call now for measuring the bootloader
read from a GPT partition, we also intend to use it for calls from
the firmware API that allow us to measure and log data from a boot
loader, such as grub. Grub will then invoke this function with a
buffer whose size it knows and will not need the ELF file size
detection.
