Well, it's at 1GB now, so I'll leave it as is.
Thanks.

True, but that's what's in current Cardhu DTS, and Harmony, Seaboard, and Ventana DTS files. Only Whistler has 0x20000000 (512MB).
How is this used, and how do we keep it in sync with what's really on the board/in the ODMDATA field?
I don't believe U-Boot uses that property from the DT. Probably the DT isn't parsed early enough for it to be useful. But if we add it to the .dts file, it may as well be correct even so. Or, perhaps we should just remove it from the U-Boot DT since it isn't useful.
Another candidate for a clean-up pass patchset over all Tegra code. For now, I'll bump it to 2GB for Dalmore (and Cardhu), since that's what's on the sample boards.
1GB would be safer for Cardhu; there are certainly very commonly used Cardhu SKUs with only 1GB of RAM. I have one. In fact, I once heard that most Linux-oriented Cardhu were 1GB and the 2GB devices were mostly used for Windows development.
