Yes, you are right. Will remove it in v2.

Yes, mtest runs fine.
I also plan to do the same for mx53 boards.

Ok, looking more closely at this I will keep the ARM2 DDR3 init as is in my v2 series.
sabrelite and sabresd does have the same DDR3 init as per the FSL U-boot source.
arm2 has a different DDR3 density, so I will not touch this file.

Ok - before you put your next version, is imx-common the right place fir it ? I mean, in imx-common we should put code that can be shared among different Freescale's SOCs. The imximage you want to share is common to some boards, not SOCs. Should we put it into a freescale's directory, let see something into boards/freescale ? There is already a boards/freescale/common, but it is PowerPC specific, so maybe it is not the right place, but we could add a new one. What do you think ?
Best regards, Stefano
