Patch 2/5 copies the value from ATAG_REVISION into the fdt "/revision"
property.

If the use of /revision is limited to being a location to hold an ATAG
value to pass to the global variable system_rev, then it would make
sense to just copy directly from the ATAG value into system_rev in the
same board file where you are copying the ATAGs.

Agreed. That would be simpler, and avoid a situation where someone relies
on the /revision property in DT to be set from the atags compat code
(preventing an upgrade to a newer bootloader), or on the system_rev variable
to be the same across multiple boot loaders, in the absence of other
kernel code setting it.

So, set system_rev only for Nokia N900? At same place where is called
save_atags()?

Yes.
