Subject: [v2] Update at91sam9m10g45 SoC and AT91SAM9M10G45-EK board to new style
Hello,
These two patches update the support of the AT91SAM9M10G45 SoC and the corresponding AT91SAM9M10G45-EK evaluation platform to the next AT91 organization.
For the moment, only the nandflash configuration is supported, the dataflash configuration will come later on.
Note however that the AT91 Ethernet driver doesn't work in the current master, due to the D-cache being enabled by c2dd0d45540397704de9b13287417d21049d34c6. The call to dcache_enable(); in arch/arm/lib/board.c must be removed.
Changes since v1: - Fixed multiple style issues - Fixed the DBGU support - Support pull-ups as done for at91sam9260
Best regards,
Thomas Petazzoni

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
