[U-Boot] U-Boot version for a new port

[Roman Mashak]

Hello,

I'm planning to make a port on a ARM926EJ-S based board. What is the
recommended way: take release or GIT version as a base ?
Thanks.

Depends on what processor you are using, atmel at91sam9 series or omap
or ti davinci 

If s, then check if your board/processor configs match with any of
these. 

Try to port their configuration & files to your board.

Look at arm versatile board, ti davinci boards for reference.

Hope this helps

It's LG's system-on-chip, consisting of main CPU (ARM926EJ-S based),
running at 216MHz, mpeg2/mpeg4/audio decoding engines, LCD interface,
UART. On-chip ROM available serves for preliminary bootloader, which
copies NAND flash content in to SDRAM.

I was considering this, but thought there would probably be something
more specific. Anyway, I need to investigate H/W more thoroughly.

Definitely work off the GIT tip of the tree.

The current window for changes is (almost) closed: there will be a 
period of stabilization.  The ToT is generally stable despite the change 
window/stabilization phases and git (rebase) is very adept at merging 
any bugfixes from the git master (git.denx.de) into your local 
development git repository.

Hints:
* Keep an unchanged mirror of git.denx.de if you are slightly paranoid 
and clone from that for your local development.
* Branches are your friend!  Always create a new branch and then 
rebase/merge/git-am from your master mirror (or git.denx.de).  If it 
works, great.  If it doesn't, figure out what is wrong.  Worst case, 
throw away the trial branch and be happy you didn't mess up your main 
branch(es).

Best regards,

I didn't work with 'git' before, mainly subversion and CVS -- need
time to master up this tool. Is it correct to issue

git clone git://www.denx.de/git/u-boot.git u-boot/

in order to obtain local copy of the current sources ?

What is ToT ?

I seem to vaguely remember a message that this one is more guaranteed to 
be up-to-date, but can't offer any useful details.

Top of Tree, or Tip of Tree.

You are right - git.denx.de is the better name, as we might decide to
split www and git services onto different servers. But for  the  time
being, both addressesare identical.
