Rob, in git commit 49a3fb455890dd9d53a18573d0998edb8332fc4a (from git://git.linaro.org/boot/u-boot-linaro-stable.git), there is:
+fdt_addr=0x1000 +pxefile_addr_r=0x700000 +kernel_addr_r=0x800000 +ramdisk_addr_r=0x01000000
Why is that first line fdt_addr not fdt_addr_r; the latter appears more often in mainline U-Boot and is what's mentioned in README too.
fdt_addr is the flash address as the README mentions. 0x1000 is not really flash, but it is the firmware provided dtb location. If we did a user loaded dtb, I would expect to use fdt_addr_r. That is also the env var that pxe boot command uses. That was my rational, but I could be persuaded that's wrong.

(as background, I'm working on a change to switch Tegra to using the standard env. var. names in mainline U-Boot and was snooping on what you'd done for Highbank!)
