Subject: [RESEND] [PATCH 0/2] kirkwood: Generalise dns325 support,
include dns320

I submitted this a while ago[0], it would be nice to see it

included

if possible. It generalises the DNS325 support so that it can be

used

for both the DNS320 and DNS325.

Luka Perkov stated I have no more questions regarding this patch,
not
sure if this counts as an ACK. The patch here is ~same, just

rebased.


Somewhat related, I have tried using tools/kwboot to boot both

NASes.

The DNS325 boots fine, however the DNS320 reports:-

Sending boot message. Please reboot the target...|
Sending boot image...
  0 % [+xmodem: Bad message

UART-boot works with kwuartboot, although only when it is killed

and

restarted. If I work out anything interesting will follow it up in
a separate thread.

Any feedback appreciated!

Finally you will two kwbimage files for two boards being supported.

BTW:

I would like to ask : what is a difference between these two files?

If

it is very small, it can be handled in early_board_init().

In that case you can keep the earlier name kwbimage.cfg as it is and

one file can be avoided.

The DNS-320 has half the RAM of the DNS-325 at different timings, so
the
difference is non-trivial. I'm not sure there would be a logical way
to
divide it up into a common setup and changes in early_board_init(). I
could have a go if you prefer though---if there's prior art somewhere
else
in u-boot please let me know and I'll have a look.


Hi Jamie

You can create a common kwbimage.cfg that suits for both the 
boards (with larger RAM size and comfortable timings for both the 
boards)


These configuration will be pushed on the Kirkwood registers before 
u-boot image kick start. Then in early_board_init() you can tuned these 
register for appropriate boards (for ex. reduce size, or tune timings 
etc.)


Please try to implement this if this sounds good.


I've had a look into this, and still not convinced it's the way to go.

Designing a kwbimage.cfg that suits both is somewhat outside my sphere of 
knowledge (both of the hardware in question and generally). e.g. can I 
assert both M_ODT[0] (as used in DNS-325) and M_ODT[1] (DNS-320) during 
write to CS0 safely, not knowing where the other pin is wired to? Will 
changing the address multiplex at runtime result in memory corruption?


Regardless, the end result would increase board-specifics. There would be 
the same information as in kwbimage.dns32[0|5].cfg now, but hidden away in 
device-specfic code and C constants instead of in a config file with a 
known format and location. This seems like a step backwards to me, and 
would certainly give headaches to anyone trying to move away from 
kwbimage.cfg to, say, devicetree.


I've implemented the other comments on the patchset, and can send these if 
you're happy with the above.


Thanks,


Regards...
Prafulla . . .
