[PATCH 0/4] ARM:sti: Add STiD127 platform and board support

[Patrice CHOTARD]

From: Patrice Chotard <patrice.chotard@st.com>

This patch-set adds basic support for STMicroelectronics STiD127 
with B2112 board support. STiD127 is dual-core ARM Cortex-A9 CPU 
to function as a cable modem or in combination with a back end
as a gateway set top box.

Wouldn't it be better to read this value from the l2 cache
controller node? I'd assume there might be more SoCs that
will need a similar change, so it's better to come up with
a solution that doesn't involve changing the kernel every
time.

Actually reading the code in this file shows that the L2 cache
initialization is the only nonstandard thing in there. We should
really find a way to get rid of the entire function.

Sorry if I missed the initial review, but can you explain
why this is needed to start with?

I think this will get rid of lot of code left in board-dt.

On ST SoCs the default value for L2 AUX_CTRL register is 0x0, so we  set
the way-size explicit here.

Unfortunately, we keep going back and forth on the L2 cache controller
setup between "it should work automatically" and "we don't want to
have configuration data in DT", where my personal opinion is that
the first one is more important here.

Now, there are a couple of properties that are defined in
Documentation/devicetree/bindings/arm/l2cc.txt to let some of the
things get set up automatically already. Can you check which bits
are missing there, if any? Are they better described as "configuration"
or "hardware" settings?

Hi Arnd,

Thanks for remarks. I will a have a look on it, but unfortunately not 
before 2 weeks.

Currently l2cc bindings has few optional properties like.

- arm,data-latency
- arm,tag-latency
- arm,dirty-latency
- arm,filter-ranges
- interrupts :
- cache-id-part:
- wt-override:

These does not include properties to set "way-size", "associativity",
"enabling prefetching", "Prefetch drop enable", "prefetch offset",
"Double linefill" and few more in prefect control register and
aux-control register.

This is not just a issue with STi SOCs, having a quick look, I can see
that few more SOCs have similar requirements to set these properties.

We could do two things to get l2 setup automatically on STi SOCS.

1> Either define these properties case-by-case basic, which might be
useful for other SOCs too.

2> Or Add new compatible string for STi SoCs so that they can
automatically setup these values in cache-l2x0.c

Am Ok with either approaches.

I suggested 1 in the past, but the objection that I saw (can't
find the email at the moment) was that the additional settings
are "configuration" rather than "hardware properties". What I'd
really need to know from you is which of properties you listed
as missing above are actually needed for your platform, and whether
they can be classified as hardware specific or just configuration.

On STi Platforms we need below properties to got for option 1.
arm,way-size;
arm,instruction-prefetch-enable;
arm,data-prefetch-enable;

we also want a property or a way to set
"Shareable attribute Override Enable" bit in the Auxiliary Control
Register, bit[22].

[PATCH 3/4] ARM: dts: Add support of STid127 Soc.

[Patrice CHOTARD]

From: Alexandre TORGUE <alexandre.torgue@st.com>

The STid127 integrates all harware components to function as a cable modem
or, in combination with a back end device, as a Gateway set top boxe.

Supported devices:
	-UART0
	-UART2

Can you add interrupt controller support to the pin controller.

Patches are in : https://lkml.org/lkml/2014/1/16/342
All these patches are due to be in v3.15.

Patches are in : https://lkml.org/lkml/2014/1/16/342
All these patches are due to be in v3.15.
