This change introduces new common function: - set_dfu_alt_info() - put dfu system and bootloader setting into $dfu_alt_info. functions declaration: - char *get_dfu_alt_system(void) - char *get_dfu_alt_boot(void) - void set_dfu_alt_info(void) and new config: - CONFIG_SET_DFU_ALT_INFO
This function can be used for auto setting dfu configuration on boot. Such feature is useful for multi board support by one u-boot binary. Each board should define two functions: - get_dfu_alt_system() - get_dfu_alt_boot()

--- Changes v2: - change config names: CONFIG_SET_DFU_BOOT_ALT to CONFIG_DFU_ALT_BOOTLOADER and CONFIG_DFU_BOOT_ALT_* to CONFIG_DFU_ALT_BOOT_* - change function name: set_dfu_boot_alt() to set_dfu_alt_boot() - remove superfluous ifdefs
Changes v3: - set $dfu_alt_info at every boot - new config: CONFIG_SET_DFU_ALT_INFO - update commit msg
Changes v4: - set_dfu_alt_info(): add checking the pointer returned by malloc
Changes v5: - set_dfu_alt_info(): remove malloc and declare cache aligned buffer - set_dfu_alt_info(): introduce CONFIG_SET_DFU_ALT_BUF_LEN --- board/samsung/common/misc.c | 41 +++++++++++++++++++++++++++++++++++++++++ include/samsung/misc.h | 6 ++++++ 2 files changed, 47 insertions(+)
