That would be very nice. There's actually some documentation in u-boot about fastboot (a README). I wonder if there's some support already?

Yes, I was told that someone (TI?) had a public tree with it. If all goes well, John (CCed) would review those, clean the patches up, upstream and integrate then into our u-boot branches so we can have them for our LEB builds as well.

Rowboat also has a decent Fastboot support in u-boot for OMAP3 http://gitorious.org/rowboat/u-boot-omap3 Not all the Fastboot commands are supported though http://wiki.tiprocessors.com/index.php/TI-Android-GingerBread-2.3-DevKit-1.0...

Hi Amit, Zach, and Alexander,

Thanks for your sharing about u-boot + Android 'fastboot' protocol/commands support. At least, patched u-boot works out of box on TI OMAP platforms.

Can we define the basic boot loader requirements of Linaro Evaluation Build (LEB) for Android at present? I think it would be essential for validation and Android platform verification purpose.

My idea is that we require abstract 'bootloader' component in Android device/linaro/common, and (patched) 'u-boot' would be the provider of 'bootloader' component in device/linaro/Linaro-Evaluation-Build-Hardware. Also, supporting firmware upgrade through 'fastboot' protocol is the recommend feature for LEB boot loader.

Does it sound reasonable?

Thanks, -jserv
