PS2: 
Can you please split this into a patch that does just the vboot uprev itself (with the commit message following the format of other uprevs like CB:73058), and a second patch that adds the code using it to coreboot? For the second patch, please also include the part where you actually want to call the function so we can review the whole picture. (Not exactly sure what your plan is there... if you want to call it from the payload, then obviously you wouldn't need this wrapper in coreboot.)
