By default (on almost all systems) the dfu env variable, which defines available alt settings, is named as "dfu_alt_info".
However on some platforms (i.e. Odroid XU3), the 'dfu_alt_info' is concatenated from other variables - namely 'dfu_alt_boot' and 'dfu_alt_system' at run time (when one types 'dfu 0 mmc 0' for first time).
'dfu_alt_boot' describes alt settings which depend on boot medium - for example boot loader's LBA sectors which are different on eMMC and SD card because of e.g. MBR/GPT.
'dfu_alt_system' describes board agnostic alt settings - like rootfs, kernel. On such system we can only append/modify this env variable.
Because of the above, we must have way to modify other than "dfu_ale_info" variable to perform tests.
