The U-Boot AT91 MCI driver is no longer the exclusive work
of Atmel.  So, I do not believe that a sole Atmel copyright
is correct for the AT91 MCI driver.

I added MMC 4.x support to the AT91 MCI driver a while back.
In response to a request for AT91 MMC 4.x support, I
submitted it to the list in the form of an informal patch
against u-boot-1.1.5_atmel1.2 on April 29, 2008.  Without
much effort, I can see that much of the code that I added is
still in the various files of the AT91 MCI driver, but my
company's copyright has been removed.  (Please note that I
never removed anyone else's copyright.)

I'm not implying that Antonio removed my company's copyright
notice, since I don't know exactly when the copyright was
removed.

However, when someone adds a significant amount of code to a
source file of a free software (GNU GPL licensed) project,
isn't it a reasonable expectation that their copyright would
be respected and thus not removed?

Can someone please clarify how copyright of derivative works is
handled within the U-Boot source code trees?  For example, how
much source code needs to be added/modified/removed to justify
a copyright notice for the changes?

Thanks,

Ken Fuchs
