[request] Support direct boot without flash

[Azkali]

Hi, I would like to know if an equivalent to fastboot boot command would be feasible in heimdall ?

No, once in download mode the bootloader side, "loki", does not have such functionality so such a thing is not possible through heimdall.

You might be interested in reading about "usb download mode" (here and here) that at least some models seem to support, and about the available commands in the sboot shell (through uart connection), and about how people managed to put sboot on sdcard and boot it in the galaxy s3
