 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

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,

If you are discussing requirements for U-Boot, and plan to get these
merged in to mainlineU-Boot one day, it would probably be a good idea
to discuss these plans on the U-Boot mailing list as well - ideally
before any design is cast in iron.

Best regards,
