[U-Boot] [PATCH v4 0/5] Android Fastboot support

[Rob Herring]

From: Rob Herring <robh at kernel.org>

This is the 2nd version since I revived the fastboot patches Sebastian 
submitted.

I'm reviving the Android Fastboot support after 2+ years since the last 
posting[1]. The previous postings had some questions about licensing 
and source of some code. I believe I've traced the history sufficiently 
that the copyrights and source information are complete and correct.

The Android code used or referenced is BSD 2-clause license. This was 
originally raised by Wolfgang that it was not compatible with GPLv2+. I 
believe that has since been demonstrated and agreed that the BSD 
2-clause license is compatible with u-boot. 

As far as the history of the code, I have traced that back. The u-boot 
code started in 2008/2009 by Tom Rix @ Windriver. This initial support 
was then adopted and extended by TI (eMMC support primarily, not 
included here) in their OMAP u-boot tree[2]. In 2011, the TI code was 
used as a basis for upstream patches by Sebastian Siewior @ Linutronix. 
The code has been rearranged quite a bit since the original, but the 
content is pretty much the same. Some of the re-arranging left stale or 
missing copyrights in the v2 version which I have corrected.

I've redone the fastboot code significantly to use the USB download 
gadget composite driver. With this, I've consolidated the fastboot 
function into a single file. I believe I've addressed all the review 
comments, but many don't apply with the re-write.

I dropped the patch adding a loadsize env variable and added config 
uptions instead to set the fastboot buffer size.

I've tested this series on a BeagleBoard.
