Subject: tools: kwboot: Remove 2s delay before sending first xmodem packet
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-logo.png?a=commitdiff_plain;h=8d3b79c4a391892f270473cfc3117d45ffe05008;p=u-boot.git

tools: kwboot: Remove 2s delay before sending first xmodem packet

This delay is not needed anymore since kwboot already handles retrying
logic for incomplete xmodem packets and also forces BootROM to flush its
input queue. Removing it decreases total transfer time.
