In both v06 and v01p (the public version), the register is in section 11.1.6.8. I guess that doesn't actually define the values of the fields, sigh. But, I can say that Tegra20 is 0x20 and Tegra30 is 0x30. For example, see: http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=blob;f=arch/arm/mach-tegra/fuse.c;h=fd703f9c1621a6d93db787e60b0d1b6314f8fb3e;hb=android-tegra-nv-2.6.39 function void tegra_get_tegraid_from_hw, and: http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=blob;f=arch/arm/mach-tegra/include/mach/hardware.h;h=d8f9bfbce42d4255d3e91db166f283a48bb4a8f2;hb=android-tegra-nv-2.6.39 for definitions of TEGRA_CHIPID_*. -- nvpublic _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
