It means "Mount /dev/mmcblk0p2 as root filesystem and boot from it"

For example a lastest version without patch for eMMC support has the high consumption problem ?
If not it is the hw registry manipulation (to activate eMMC) which generates the problem

Got it thanks! Just as I thought. What made me confused about that command is it is used for Kubuntu mobile. The whole image is put on sd card which is an external card and should be /dev/mmcblk1p2 so I wondered why is it pointing on /dev/mmcblk0p2 yet it boots perfectly.

Hi Pali! A friend of mine did lookup on the power consumption issue from her n900, tested every commit from git and said that uboot power consumption was ok before this commit.

A supposition :
This header adds value definitions (#define) used by other u-boot sources.
If the #define are missing the source code does nothing (or uses default values) but if the #define are present then they are used during Hw config and some of these #define generate misconfigured Hw

I got a feeling that it would map /dev/mmcblk0p2 as as root partition for the booted OS but I'm not sure that's why I asked.
