So, 128 MB ?

Or 256 MB ?

Also, could you review the patch from Angelo adding support for another
board from ACME:

Thanks,

Ouch, i'll send V2 with two configs (got 256MB hardware here, with the 
128MB config the memory is reduced as expected).

The Arietta is a stripped down Aria, i'll take a look but i have no way 
of testing it since i don't have one.
Having get that out of the way, it'll probably work just fine on the 
Aria i think.
Regards.

One thing that was bothering me in the contribution from Angelo was
specifically the need for two defconfigs. I guess there's no way to
runtime detect the memory size, and therefore build a single
at91bootstrap3 for both board configurations?

I really only asked for patch review, not testing. So not having the HW
is not a good excuse :-)

Thanks!

It doesn't seem to be the case at this point.
I think it could be doable via 2nd stage (u-boot) but for an SD-boot i 
don't see much benefit in having it around (that would change if eMMC 
was involved, but it generally isn't the case, specially for the Arietta).

Yes, yes, i know, i was just stating that it'll be a quick look with 
Aria-knowledge :)
Regards.

+Build instructions
+==================
+
+As a regular user configure and then build:
+
+$ make acmesystems_aria_g25_defconfig
+$ make
+
+Writing to the MicroSD card
+===========================
+
+Assuming your Aria G25 baseboard has a MicroSD socket, for example with
+the Terra baseboard, you'll need a blank MicroSD (obviously) initialized
+in a particular way to be able to boot from it.
+
+Assuming the card is seen as /dev/sdb in your PC/laptop/other device
+you'll need to run the following commands as root or via sudo.
+
+Make sure all of the card partitions are unmounted before starting.
+
+First we'll need to create two partitions:
+
+# sfdisk -uM /dev/sdb <<EOF
+,32,6
+;
+EOF
+
+Then we'll need to create the empty filesystems:
+
+# mkdosfs -n SD_BOOT /dev/sdb1
+# mkfs.ext4 -L SD_ROOT /dev/sdb2
+
+We'll populate the first partition (boot) with the relevant files:
+
+# mount /dev/sdb1 /mnt
+# cp output/images/at91bootstrap.bin /mnt/BOOT.BIN
+# cp output/images/zImage /mnt
+# cp output/images/at91-ariag25.dtb /mnt
+# umount /mnt
+
+And the root filesystem afterwards:
+
+# mount /dev/sdb2 /mnt
+# tar -C /mnt output/images/rootfs.tar
+# umount /mnt
+
+You're done, insert the MicroSD card in the slot and enjoy.
+
