I assumed this would be in Mainline u-boot, but apparently not.
On closer inspection of the internal ST-Ericsson u-boot, this
functionality appears to be provided by patches which currently
exist as delta. So in essence, the bootloader you use will have
to be patched in a similar way for you to retrieve information
surrounding bootloader boot times.

And there was me thinking it was magic. ;)
