[U-Boot] U-boot as a mass storage device and DFU support

[Jacky Lam]

Dear all,

Could anyone kindly tell me if u-boot supports itself as a mass storage
device?

Or if u-boot main stream support the a protocol so call USB
DFU(Universal Serial Bus Device Firmware Upgrade)?
I have first seen this on openmoko.org and seems they use u-boot as
well. However, when I look at the newest u-boot (1.3.4). It seems no
code is about it. I don't know if I have overlooked something.

Thanks.

BR,
Jacky

no, maybe MTP will be simplest to implement

	Would it be appropriate to send the patch if I am not the original
author???

If you make sure that the patch works and maintain the chain of
Signed-off-by entries, then yes, of course.

Note that you will probably also have to answer questions related to
the patch, and/or have to change the code according to feedback and
review comments you might receive.

Best regards,

No, it does not. A lot of infrastructure for that is missing, for
example writable file systems to name just one.

No.

U-Boot 1.3.4 is actually pretty old. It is definitely NOT the latest
release - that's 2008.10 (with 2009.01 to be released soon).
