We don't tend to use LOADADDR in any of the default boot scripts any 
more. Rather, we explicitly load files to a "semantic" location 
indicated by one of the following variables in tegra124-common.h:

#define MEM_LAYOUT_ENV_SETTINGS \
         "scriptaddr=0x90000000\0" \
         "pxefile_addr_r=0x90100000\0" \
         "kernel_addr_r=0x81000000\0" \
         "fdt_addr_r=0x82000000\0" \
         "ramdisk_addr_r=0x82100000\0"

Perhaps the ChromeOS boot scripts could be adjusted to use one/some of 
those variables?

If the value of CONFIG_LOADADDR isn't appropriate, perhaps we should fix 
it for all Tegra SoCs/boards?
