I believe that I claimed to have tested this in the past but that
my testing was by booting a config to userspace that as it happens
did not require to timer to get that far.
I now believe there is a minor error: the interrupt number should be
(139 - 32 =) 107 rather than 139.
This allows a system with this and the related genmai patch applied
on top of renesas-next-v3.16-rc3-20140715 to boot to uerspace
when compiled with shmobile_defconfig (+ an initrd).
Without the irq number change the boot gets stuck in
ip_auto_config (which presumably sleeps).
Laurent, should I squash the following in and queue-up the result?

Not at all. I've made the same one several times myself.

No more device needs to be added from platform code when booting the
reference platform, move MTU2 registration from setup-r7s72100.c to
board-genmai.c and remove the now empty r7s72100_add_dt_devices()
function.
As the genmai_add_standard_devices() function is now identical to the
default init_machine implementation, remove it as well.

Hi Laurent,
I am having some trouble with this patch.
In particular the shmobile defconfig with an initrd added
(to compensate for the lack of ethernet and thus NFS) does
not seem to make it to userspace with this patch applied :(
I am dropping it for now, but could you look into it?
For the record it seems to stop right near the end.
A bad boot looks like this:
