ARM: Initial SuperH Mobile ARM support
[PATCH 01/06] ARM: SuperH Mobile ARM, sh7367 and G3EVM support
[PATCH 02/06] ARM: Add sh7377 and G4EVM support
[PATCH 03/06] ARM: Add sh7372 and AP4EVB support
[PATCH 04/06] sh: Build drivers/sh for SuperH Mobile ARM
[PATCH 05/06] sh: Let INTC set IRQF_VALID on ARM platforms
[PATCH 06/06] sh-sci: Preliminary SuperH Mobile ARM support
Here comes a set of SuperH Mobile ARM patches. Nothing ground
breaking really, just the bare minimum to get a kernel up and
running with serial and timer on G3EVM, G4EVM and AP4EVB.
Features:
- Console: Serial console using drivers/serial/sh-sci.c
- Timer: Early platform driver using drivers/clocksource/sh_cmt.c
- Interrupts: Minimal INTC support using drivers/sh/intc.c
- Clocks: Dummy static implementation to enable above drivers
- Defconfigs: Omitted for now to simplify review
On top of this there will be a bunch of feature patches for
the interrupt controller, gpio, clock framework, runtime pm
and of course driver support.
I intend to throw this into a git repository at some point,
but I may have to rework these patches a bit first depending
on feedback.
Please let me know if there is anything you want me to rework
and perhaps if you have some shared ARM code that you want me
to spend time on. Thanks!

From: Magnus Damm <damm@opensource.se>
This patch contains the SuperH Mobile ARM base support together
with sh7367 CPU and G3EVM board support. Only timer, serial
console and NOR flash are supported at this point. Patches for
the interrupt controller, pinmux support, clock framework and
runtime pm will be submitted as feature patches on top of this.

* [PATCH 01/06] ARM: SuperH Mobile ARM, sh7367 and G3EVM support
@ 2010-01-28 12:40 ` Magnus Damm
0 siblings, 0 replies; 32+ messages in thread
From: Magnus Damm @ 2010-01-28 12:40 UTC (permalink / raw)
To: linux-arm-kernel
From: Magnus Damm <damm@opensource.se>
This patch contains the SuperH Mobile ARM base support together
with sh7367 CPU and G3EVM board support. Only timer, serial
console and NOR flash are supported at this point. Patches for
the interrupt controller, pinmux support, clock framework and
runtime pm will be submitted as feature patches on top of this.

To: linux
Cc: eric.y.miao, tony, linux-kernel, khilman, lethal, ben-linux,
Magnus Damm, linux-arm-kernel
From: Magnus Damm <damm@opensource.se>
This patch adds base support for the SuperH Mobile ARM processor
sh7377 together with G4EVM board support. Only timer, serial
console and NOR flash are supported at this point. Patches for
the interrupt controller, pinmux support, clock framework and
runtime pm will be submitted as feature patches on top of this.
Signed-off-by: Magnus Damm <damm@opensource.se>

Applies on top of linux-next 20100119 and the sh7367 patch.

* [PATCH 02/06] ARM: Add sh7377 and G4EVM support
@ 2010-01-28 12:40 ` Magnus Damm
0 siblings, 0 replies; 32+ messages in thread
From: Magnus Damm @ 2010-01-28 12:40 UTC (permalink / raw)
To: linux-arm-kernel
From: Magnus Damm <damm@opensource.se>
This patch adds base support for the SuperH Mobile ARM processor
sh7377 together with G4EVM board support. Only timer, serial
console and NOR flash are supported at this point. Patches for
the interrupt controller, pinmux support, clock framework and
runtime pm will be submitted as feature patches on top of this.
Signed-off-by: Magnus Damm <damm@opensource.se>

Applies on top of linux-next 20100119 and the sh7367 patch.

To: linux
Cc: eric.y.miao, tony, linux-kernel, khilman, lethal, ben-linux,
Magnus Damm, linux-arm-kernel
From: Magnus Damm <damm@opensource.se>
This patch adds base support for the SuperH Mobile ARM processor
sh7372 together with AP4EVB board support. Only timer, serial
console and NOR flash are supported at this point. Patches for
the interrupt controller, pinmux support, clock framework and
runtime pm will be submitted as feature patches on top of this.
The mach-type entry has been submitted but is included here for now.
Signed-off-by: Magnus Damm <damm@opensource.se>

Applies on top of linux-next 20100119 and the sh7367+sh7377 patches.

* [PATCH 03/06] ARM: Add sh7372 and AP4EVB support
@ 2010-01-28 12:41 ` Magnus Damm
0 siblings, 0 replies; 32+ messages in thread
From: Magnus Damm @ 2010-01-28 12:41 UTC (permalink / raw)
To: linux-arm-kernel
From: Magnus Damm <damm@opensource.se>
This patch adds base support for the SuperH Mobile ARM processor
sh7372 together with AP4EVB board support. Only timer, serial
console and NOR flash are supported at this point. Patches for
the interrupt controller, pinmux support, clock framework and
runtime pm will be submitted as feature patches on top of this.
The mach-type entry has been submitted but is included here for now.
Signed-off-by: Magnus Damm <damm@opensource.se>

Applies on top of linux-next 20100119 and the sh7367+sh7377 patches.

Reuse the SuperH INTC code on ARM by using set_irq_flags()
to set IRQF_VALID on ARM platforms. Reworking the shared ARM
interrupt code and removing IRQF_VALID is another option.

Add preliminary SuperH Mobile ARM support to the sh-sci
driver. Enough to get serial console working. Needs more
work. Is really disconnected from the ARM support code
but is included here for completeness.

I guess you can't do a lot about this because of arch/sh, but over in ARM
land, we use clkdev to get the clock primerily by the device name rather
than a string passed around; this is how the clk API is meant to be used.

This should be CONFIG_ARM rather than ARCH_SHMOBILE, as it's hardly
SH-Mobile specific.

SCIF_ONLY should be killed off, nothing is checking for it these days. I
thought they were all gone already, but it looks like SH7757 snuck one

At this early stage there is not so much to do. When I get around to
implement the clock framework and runtime pm for SuperH Mobile ARM
then I'll have a close look at clkdev.
I'll update and resend these patches next week.

I superh actually manufacturer? And can we get shorter name than

SH-Mobile (G series, in this case) is a line of SH/ARM multi-cores. They
contain both SH and ARM MPUs and are built up almost entirely on SH IP
blocks. There are some SH-Mobiles that are SH-only, and those are taken
care of in arch/sh/ as normal. Most of the shared code sits in drivers/sh
and so forth, requiring fairly little glue on the ARM architecture side.
As support for these CPUs is extended, we'll likely see more of arch/sh/
being generalized. There's likely not going to be enough that is directly
reusable between the two to warrant a split out architecture directory of
its own, but we'll see how it goes.
It's forseeable that we will also see support for the same CPU in
arch/sh/ aimed at the SH MPU, and that we can have linux running on both
the SH and the ARM at the same time sharing the same peripheral domain.
However, all of these things are out of scope for this patch set, which
is just getting the groundwork established for the ARM MPU.
> I superh actually manufacturer? And can we get shorter name than

shmobile is what the line is called, and matches the naming scheme we
already have in-tree today. Changing that around would only lead to more
confusion. It's also not really any longer than many of the other mach
types, so I don't really see the point.

Jaysis, that's one odd bird. There must be some upside to designing

Most of it comes down to customer requirements, where the application
stack is primarily running on a single MPU and the other is primarily
used as a co-processor. In the Japanese cellular market (what this series
was designed for) many people have a lot of existing ITRON code tied to
one architecture or the other that they don't wish to part with, are
unable to port, etc. a lot of that ends up being multimedia bits, but
people have done other things with it, too. We've also done SH/M32R
multi-cores in the past for similar reasons, although those had a limited
production run.
The multiple kernels on multiple CPUs thing is pretty standard for the
Japanese market at least, we face similar issues on SH SMP where we have
a need for lightweight CPU and memory hotplug/unplug in order to offline
different CPUs temporarily for one-shot ITRON/uITRON applications (which
gets to be tricky if that CPUs memory is an active NUMA node that we've
already spread allocations to), this is something quite common in
automotive at least.
The real problem with ITRON is that many of the existing applications
do fairly questionable things with register accesses, which can cause
troubles for things like dynamic clock gating and the like. On the other
hand, it only runs in a single address space, so simply paravirtualizing
the parts we care about should be lightweight enough. Outside of the
Japanese market, ITRON and its variants are much more of an unknown, so
providing Linux for both cores is becoming gradually more important. The
previous generations all contained an integrated cellular baseband which
largely restricted it to the domestic market, although this has been
changing over the last couple of years with multi-band FOMA becoming more
commonplace. In any event, things like AP4 are more intended for general
use and decouple the baseband completely.
The domestic market will likely gradually transition over to Linux on
both cores, but it will take some time, and even then we'll likely never
be rid of ITRON completely (and especially not uITRON). These CPUs have
been in the majority of Japanese cell phones for almost a decade, with a
lot of the underlying code changing very little. The ARM MPU itself is a
new addition on the side that was only added a couple of years ago, but
we still have to wait and see if people are able to make effective use of
both.
As far as public information, there's very little in either english or
japanese. I couldn't really point you at anything specific that you
couldn't find with google. In any event, now that these sorts of things
are no longer restricted to the Japanese domestic market we'll hopefully
be able to employ a greater degree of transparency.

we still have to wait and see if people are able to make effective use of
both.
As far as public information, there's very little in either english or
japanese. I couldn't really point you at anything specific that you
couldn't find with google. In any event, now that these sorts of things
are no longer restricted to the Japanese domestic market we'll hopefully
be able to employ a greater degree of transparency.
