+Measured Boot +=====================
This completely misses o describe measured boot with UEFI.
@Ilias, do you want to add that in a follow up patch?
Yes, I'll do that once I pull Eddie's patches
Cheers /Ilias
+U-Boot can perform a measured boot, the process of hashing various components +of the boot process, extending the results in the TPM and logging the +component's measurement in memory for the operating system to consume.
+Requirements +---------------------
+* A hardware TPM 2.0 supported by the U-Boot drivers +* CONFIG_TPM=y +* CONFIG_MEASURED_BOOT=y +* Device-tree configuration of the TPM device to specify the memory area
- for event logging. The TPM device node must either contain a phandle to
- a reserved memory region or "linux,sml-base" and "linux,sml-size"
- indicating the address and size of the memory region. An example can be
- found in arch/sandbox/dts/test.dts
+* The operating system must also be configured to use the memory regions
- specified in the U-Boot device-tree in order to make use of the event
- log.
Please, provide enough information such that a reader can set this up. This should include example code.
Best regards
Heinrich
