Re: [U-Boot] Mainline u-boot on socfpga (SocKit) board

Hi!

  I know that mainline U-Boot SPL is quite far from working on
  socfpga... but would like to ask, what is the status of U-Boot
  proper. That should work on socfpga, right? Or are there some pieces
  missing?
  
  I tried 
  
  commit 173d294b94cfec10063a5be40934d6d8fb7981ce
  Merge: 33b0f7b 870e0bd
  Author: Tom Rini tr...@ti.com
  Date:   Tue May 6 14:55:45 2014 -0400
  
  Merge branch 'serial' of git://www.denx.de/git/u-boot-microblaze
  
  and it just dies with no output.
  
  I'd really like to get something close to mainline working, so that I
  can generate patches etc.
  
 
 The missing piece here is the SDRAM driver. This is a big piece as
 U-boot require the SDRAM to run. As of now, I am enhancing the existing
 SDRAM drivers to ensure its compliance with the coding standard. 

I know about missing SDRAM driver, but that is in u-boot-spl, not
u-boot (right?). I know u-boot-spl is not feasible right now, but I'd
like to get at least u-boot proper to work. Is that something else
that is known to be missing?

 But nevertheless, it poses another challenge when come to license. The
 driver is currently licensed under BSD-3 clause. Wonder can we upstream
 BSD-3 clause code? Any advise would be appreciated.

So: You are copyright holders, you can change the license. (Right?)

Second, it seems that BSD-3 clause is actually GPL-compatible:

Best regards,
Pavel

https://www.gnu.org/licenses/license-list.html#GPLCompatibleLicenses

Modified BSD license (#ModifiedBSD)
This is the original BSD license, modified by removal of the
advertising clause. It is a lax, permissive non-copyleft free software
license, compatible with the GNU GPL.

This license is sometimes referred to as the 3-clause BSD license.

The modified BSD license is not bad, as lax permissive licenses go,
though the Apache 2.0 license is preferable. However, it is risky to
recommend use of “the BSD license”, even for special cases such as
small programs, because confusion could easily occur and lead to use
of the flawed original BSD license. To avoid this risk, you can
suggest the X11 license instead. The X11 license and the modified
revised BSD license are more or less equivalent.

However, the Apache 2.0 license is better for substantial programs,
since it prevents patent treachery.

Dear Chin Liang See,

In message 1399544922.2064.19.ca...@clsee-virtualbox.altera.com you wrote:

It's your code, so why can't you relicense it under GPL?  Why was it
not licensed under GPL from the beginning when it'sbeen written for
U-Boot?

Technically, the original BSD license, modified by removal of the
advertising clause (sometimes referred to as the 3-clause BSD
license) is considered to be compatible with the GNU GPL.

Best regards,
Viele Grüße,

Wolfgang Denk
