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.
