From 5661f08a71446ab0ffb5bcf595709027e68f10fa Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Wed, 16 Aug 2017 11:00:51 -0700 Subject: usb: gadget: add SDP driver MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add SDP (Serial Downloader Protocol) implementation for U-Boot. The protocol is used in NXP SoC's boot ROM and allows to download program images. Beside that, it can also be used to read/write registers and download complete Device Configuration Data (DCD) sets. This basic implementation supports downloading images with the imx header format reading and writing registers.
