[PATCH 1/2] Boottime: A tool for automatic measurement of kernel/bootloader boot time

+/* for automatic boot timing testcases */
+#define ATAG_BOOTTIME  0x41000403
Where can I refer this ATAG usage? can you point out the reference URL
or patches?
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. ;)
Okay, so I'm going through the motions of upstreaming this magic
now. Please see the link below for reference:
