[U-Boot] SPL Dfu update

[Michael Trimarchi]

Hi Lukasz

We have discussed during the u-boot mini-summit the possibility to have
the dfu update from SPL. Right now I'm trying to understand what is the best
way to do:


void spl_dfu_load_image()
{
        int rv;

        env_init();
        env_relocate();
        setenv("dfu_alt_info", DFU_BOARD_FLASHINFO);
        board_usb_init();
        g_dnl_register(s);

One option could be do the same of do_dfu command and let upload
all the image that is needed to flash and the issue a usb reset. I don't sure
if the reset can be triggered and then do a cpu board reset and let it boot
from the booting device.

What is for you the best approch?

Michael
