Yes, this will require a little more work as the fastboot side is OK with "DRA722", the question I have is can we construct that similar to what omap_rev_string() does? Thanks! -- Tom

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 arch/arm/include/asm/omap_common.h | 6 ++ arch/arm/mach-omap2/utils.c | 115 +++++++++++++++++++++++++++++++++++++ 2 files changed, 121 insertions(+)
