This patch reuses new option, which allows us to expose variables from environment to "fastboot getvar" command. Those variables must be of "fastboot.%s" format.
Signed-off-by: Sam Protsenko semen.protsenko@linaro.org --- Changes in v2: - use get_device_type() instead of omap_get_cpu_type() - guard omap_set_fastboot_vars() with CONFIG_FASTBOOT_FLASH - use correct board names
