When I set up Tegra's config files to put the environment into eMMC, I assumed that CONFIG_ENV_OFFSET was a linearized address relative to the start of the eMMC device, and spanning HW partitions boot0, boot1, general* and the user area in order. However, it turns out that the offset is actually relative to the beginning of the user area. Hence, the environment block ended up in a different location to expected and documented. Set CONFIG_SYS_MMC_ENV_PART=2 (boot1) to solve this, and adjust CONFIG_ENV_OFFSET to be relative to the start of boot1, not the entire eMMC.
