+/* for automatic boot timing testcases */ +#define ATAG_BOOTTIME 0x41000403Where 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: http://marc.info/?l=u-boot&m=135342273317337&w=2 -- Lee Jones Linaro ST-Ericsson Landing Team Lead Linaro.org ? Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog
