dfu: Provide means to find difference between dfu-util -e and -R
This commit provides distinction between DFU device detach and reset. The -R behavior is preserved with proper handling of the dfu-util's -e switch, which detach the DFU device. By running dfu-util -e; one can force device to finish the execution of dfu command on target and execute some other scripted commands. Moreover, some naming has been changed - the dfu_reset() method now is known as dfu_detach(). New name better reflects the purpose of the code. It was also necessary to increase the number of usb_gadget_handle_interrupts() calls since we also must wait for detection of the USB reset event. Example usage: 1. -e (detach) switch dfu-util -a0 -D file1.bin;dfu-util -a3 -D uImage;dfu-util -e access to u-boot prompt. 2. -R (reset) switch dfu-util -a0 -D file1.bin;dfu-util -R -a3 -D uImage target board reset Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Reviewed-by: Stephen Warren <swarren@nvidia.com> Tested-by: Stephen Warren <swarren@nvidia.com>
