Removal of board from MAKEALL missing...

Configuring for at91sam9m10g45ek_nandflash - Board: at91sam9m10g45ek,
Options: AT91SAM9M10G45,SYS_USE_NANDFLASH
at91sam9m10g45ek.c: In function ‘board_early_init_f’:
at91sam9m10g45ek.c:256:1: warning: control reaches end of non-void
function
   text	   data	    bss	    dec	    hex	filename
 201534	  32116	  71760	 305410	  4a902	./u-boot

AND this board's early_init_f is quite different from the other atmel
boards, also the place of calling at91_seriald_hw_init() is different
from them.
Please verify that this is OK.

Thanks,
Reinhard

If at91_seriald_hw_init() isn't called in early_init_f, then the
"U-Boot 2011.06-.... (Aug 04 2011 ...)" message isn't displayed on the
debug serial port.

That would mean, that the other boards would not display the message
either..!? I cannot verify this, I can only verify seamless build..

So please fix the two issues I mentioned: board removal from MAKEALL and
missing return value of board_early_init_f().

Thank you,
Reinhard

I guess so.

However, I have just taken an AT91SAM9261-EK and it seems that U-Boot
from atmel/master does not work at all.

First, the AT91Bootstrap binary provided by Atmel only loads 0x33900
bytes from the Dataflash, but current U-Boot binaries are larger than
that. This might surprise people trying to mix a recent version of
U-Boot with the normal AT91Bootstrap configuration on this platform.

Unfortunately, even with this fix in place, U-Boot still doesn't show
any sign of life on this platform...

Regards,

Thomas

The (maximum) size of the image to load is hardcoded into at91bootstrap.
For most boards (including at91sam9m10g45-ek) this is 0x33900 if
loading from DataFlash and 0x40000 if loading from NAND.

So if you didn't modify your at91bootstrap, you should get the same
problem on AT91SAM9M10G45-EK if booting from DataFlash.

Correct. The thing is that I only tested the AT91SAM9M10G45-EK support
on Nandflash, as I haven't had the time to get the Dataflash support to
work again in the current U-Boot.

I have a custom board similar to AT91SAM9M10G45-EK here which boots
from Dataflash, but it uses an old 1.3.4 U-Boot (which I'd like to
upgrade), for which the binary is only 152K, which is less than
0x33900. I'll try to get a modern U-Boot working with Dataflash support
on AT91SAM9M10G45-EK, and this will require a small modification in
AT91Bootstrap.

It is a bit amazing to see that the size of U-Boot has increased from
154912 bytes in version 1.3.4 to 233252 bytes in the current Git (and
the latter has no support for Dataflash, while the former does).

Regards,

Thomas
