[U-Boot-Users] New architecture -- TI DaVinci

Sergey

	Apologies - you fooled me with the "New Architecture". 
I did a quick google & found the TMS320DM6443 was a DSP, so assumed it
would be a new DSP architecture, 
rather than being part of arm. 

I don't always know where ARM cores have been used - it helps if the
email subject mentions ARM.

I'll add your patch to my list.

I am also very interested in this. I have started hacking at supporting 
the Lyrtech SFF SDR board, and trying to do so in a way the patches can 
be accepted. (I am trying to figure out git and the coding standards).

My work is based of the TI work (I think, the patch came via the 
internet) and I have looked at Sergey's patch, although I think he needs 
to rework the multiple board support.

I would like to see us get some stuff moving into the mainline git so we 
can build some structure for people to work with. I am really thrashing 
about trying to get NAND support going. I know people have solved this 
problem, but I can't see the right way to go.

The davinci people really need to get this stuff flowing into git.

I can rework anything and I'm thinking about making a davinci tree with
separate board subdirs but I don't want to waste my time redoing that thing
again and again. I would like to patch anything that is in the git tree.

As a matter of fact that my patch works just fine on different boards with
small and large page NAND devices. That's what we are using now without any
problems. Sure it works on DV-EVM... Please let me know what problems do you
have with NAND and I'll probably be able to help you...

I do also have the initial bootloader that works on serial port and allows
to load user app in DDR2, run it, write itself in NAND to act as an initial
NAND bootloader that loads user app (e.g. U-Boot) and provides for simple
command line debugging. That is also, IMHO, belongs to U-Boot, probably in a
separate subdir or whatever. There is lot of those that used on differnt
platforms and I think it would be really nice to have those in U-Boot tree
to be able to bring up a new board from a virgin state without wasting time
writing one...

I also fixed the problem with Large Page NAND devices where U-Boot hang
after "NAND: xxx MiB" so everything works now.

This should be propagated to the main tree in order to make necessary
patches against it.

Or is it already all obsolete in the light of new shiny U-Boot with new
CONFIG_* options and I have to redo everything from scratch?

	Currently working on a software release.
I hope to get some time for U-Boot next week....

Please post this NAND related patch (and other non DaVince related fixes too) 
to the list. I'll try to review and apply it quickly. Thanks.

No, please continue with the current U-Boot repository for now. The "new" 
U-Boot version is, as far as I understand, not production ready yet.

Best regards,
Stefan
