Dear Simon Glass,
In message 1326590698-7767-14-git-send-email-sjg@chromium.org you wrote:
This defines the basics of a new boot time measurement feature. This allows logging of very accurate time measurements as the boot proceeds, by using an available microsecond counter.
To enable the feature, define CONFIG_BOOTSTAGE in your board config file. Also available is CONFIG_BOOTSTAGE_REPORT which will cause a report to be printed just before handing off to the OS.
Most IDs are not named at this stage. For that I would first like to renumber them all.
Hm.... I'm not sure what happened.
I am positively sure (and I just checked again in the bash history) that I did apply the correct version of "[PATCH v3 11/15] timer: add microsecond boot func".
However, the repository appears to have an old version instead:

I cannot reproduce it, but it seems patchworked palyed some trick on me (it has also beenx extremely slow last night - eventually some works was going on there?).
Anyway. Fact is, the current mainline code contains a broken patch, which breaks for example the PMC440 board:
Configuring for PMC440 board... /work/wd/tmp-ppc/examples/api/time.o: In function `__timer_get_boot_us': /home/wd/git/u-boot/work/lib/time.c:60: undefined reference to `get_timer' /home/wd/git/u-boot/work/lib/time.c:61: undefined reference to `get_timer' make[1]: *** [/work/wd/tmp-ppc/examples/api/demo] Error 1
Can you please have a look and provide an incremental patch to bring mainline back in sync with your current code base?
Thanks.
Best regards,
Wolfgang Denk
