If you have less than 128MB DDR we can sort something out, but if you have 256MB it's really advised to use 0x88000000 for the DT (see Documentation/arm/Booting in the kernel).

Overo doesn't pull in the configuration from include/configs/ti_armv7_common.h where DEFAULT_LINUX_BOOT_ENV is defined. Might a v2 using the settings defined by DEFAULT_LINUX_BOOT_ENV in the overo config be acceptable? --Ash

I'd like to start by seeing if we can adopt the files (ti_omap3_common.h which grabs ti_armv7_common.h). The intention is to have the really common parts there and the board specific elsewhere. It's indeed not quite perfect and we probably need to push a few things back up to the board, even if they're repeated frequently.

As this is a rather distinct change, I'm sending an additional patch that switches Overo to ti_omap3_common and DEFAULT_LINUX_BOOT_ENV rather than amending the previous patch series. I hope this is appropriate and acceptable as I wasn't sure the policy on such patches after the close date for the merge window. Another newbie question: should I be basing submitted patches off u-boot-ti/master (as I'm using TI chips) or u-boot/master? --Ash

Totally correct---good catch.
I'll send a v2 for this series rebased on u-boot-ti/master and also
include this [1] patch. Hopefully this is correct.
