Hi Przemyslaw,
I have a question.
"dfu_alt_bootloader" env is settings successfully
dfu_alt_bootloader=u-boot raw 0x3e 0x800 mmcpart 1
But, In order to replace bootloader binary in thor mode, How can I use the "dfu_alt_bootloader" env?
DFU gadget use "dfu_alt_info" env for DFU entities configuration.
Is there any patch to support multiple "dfu_alt" environment, or "dfu_alt_info" environment settings to use "dfu_alt_bootloader" env?
best regards, Inha Song.

This change adds new function:
- set_dfu_boot_alt(bootmode) - where bootmode is the value of Exynos ompin[5:1] masked with BOOT_MODE(x) macro.
This change is useful for devices with more than one boot device, e.g. with a separated SD and eMMC slots. Different dfu entities are required for SD and eMMC cards. The board config should define:
- CONFIG_MISC_COMMON
- CONFIG_SET_DFU_BOOT_ALT
and at least one of below alt setting:
- CONFIG_DFU_BOOT_ALT_SD, e.g: "u-boot raw 1 2048"
- CONFIG_DFU_BOOT_ALT_eMMC, e.g: "u-boot raw 0 2048 mmcpart 1"
