 ### SMMSTORE
 SMMSTORE, or SMMSTOREv2, are SMM mediated drivers to read from write to and erase a predefined region in the flash. This can be used by the OS or the payload to implement persistent storage to hold for instance configuration data, without needing to implement a (platform specific) storage driver in the payload itself.
-For more details about actual implementation of SMMSTORE and SMMSTOREv2, we refer to coreboot's documentation [[7]](#), [[8]](#). In practice SMMSTORE(/v2) is used if coreboot is built with EDK2 as payload. If that's the case, SMMSTORE(/v2) is used to store UEFI Secureboot Keys

+For more details about actual implementation of SMMSTORE and SMMSTOREv2, we refer to coreboot's documentation [[7]](#), [[8]](#). In practice SMMSTORE(/v2) is used if coreboot is built with EDK2 as payload. Such configuration uses UEFI Secureboot, which relies on Authenticated SMM variable to store Secureboot Keys [[9]](#9).
+TODO: finish up this section.
