Hi,

recently we wanted to update xilinx intc driver and we found that function
which we wanted to remove is still wired by ancient Xilinx PowerPC
platforms. Here is the thread about it.
https://lore.kernel.org/linux-next/48d3232d-0f1d-42ea-3109-f44bbabfa2e8@xilinx.com/

I have been talking about it internally and there is no interest in these
platforms and it is also orphan for quite a long time. None is really
running/testing these platforms regularly that's why I think it makes sense
to remove them also with drivers which are specific to this platform.

U-Boot support was removed in 2017 without anybody complain about it
https://github.com/Xilinx/u-boot-xlnx/commit/98f705c9cefdfdba62c069821bbba10273a0a8ed

Based on current ppc/next.

If anyone has any objection about it, please let me know.

Thanks,
Michal

The latest Xilinx design tools called ISE and EDK has been released in
October 2013. New tool doesn't support any PPC405/PPC440 new designs.
These platforms are no longer supported and tested.

PowerPC 405/440 port is orphan from 2013 by
commit cdeb89943bfc ("MAINTAINERS: Fix incorrect status tag") and
commit 19624236cce1 ("MAINTAINERS: Update Grant's email address and maintainership")
that's why it is time to remove the support fot these platforms.

-   Some IP cores actually implement 2 or more logical devices.  In
-   this case, the device should still describe the whole IP core with
-   a single node and add a child node for each logical device.  The
-   ranges property can be used to translate from parent IP-core to the
-   registers of each device.  In addition, the parent node should be
-   compatible with the bus type 'xlnx,compound', and should contain
-   #address-cells and #size-cells, as with any other bus.  (Note: this
-   makes the assumption that both logical devices have the same bus
-   binding.  If this is not true, then separate nodes should be used
-   for each logical device).  The 'cell-index' property can be used to
-   enumerate logical devices within an IP core.  For example, the
-   following is the system.mhs entry for the dual ps2 controller found
-   on the ml403 reference design.
-
-	BEGIN opb_ps2_dual_ref
-		PARAMETER INSTANCE = opb_ps2_dual_ref_0
-		PARAMETER HW_VER = 1.00.a
-		PARAMETER C_BASEADDR = 0xA9000000

-		PORT Clkin1 = ps2_clk_rx_1

-		PORT Clkpd1 = ps2_clk_tx_1
-		PORT Clkpd2 = ps2_clk_tx_2
-		PORT Rx1 = ps2_d_rx_1
-		PORT Rx2 = ps2_d_rx_2
-		PORT Txpd1 = ps2_d_tx_1
-		PORT Txpd2 = ps2_d_tx_2
-	END
-
-   It would result in the following device tree nodes:
-
-	opb_ps2_dual_ref_0: opb-ps2-dual-ref@a9000000 {
-		#address-cells = <1>;
-		#size-cells = <1>;
-		compatible = "xlnx,compound";
-		ranges = <0 a9000000 2000>;
-		// If this device had extra parameters, then they would
-		// go here.
-		ps2@0 {
-			compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
-			reg = <0 40>;
-			interrupt-parent = <&opb_intc_0>;

This looks reasonable to me as well, in particular as the code only
supports the two
ppc44x virtex developer boards and no commercial products.

It does raise a follow-up question about ppc40x though: is it time to
retire all of it?
The other ppc405 machines appear to have seen even fewer updates after the
OpenBlockS 600 got added in 2011, so it's possible nobody is using them any more
with modern kernels.

I see that OpenWRT removed both ppc40x and ppc44x exactly a year ago after
they had not been maintained for years.

However, 44x (in its ppc476 incarnation) is clearly still is used
through the fsp2 platform,
and can not be deprecated at least until that is known to have stopped
getting kernel
updates.

Who knows?

I have in possession nice WD My Book Live, based on this architecture, and I
won't it gone from modern kernel support. OTOH I understand that amount of real
users not too big.

Ah, and I have Amiga board, but that one is being used only for testing, so,
I don't care much.

According to https://openwrt.org/toh/wd/mybooklive, that one is based on
APM82181/ppc464, so it is about several generations newer than what I
asked about (ppc40x).

I think there are a couple of ppc440 based Amiga boards, but again, not 405
to my knowledge.

Ah, you are right. No objections from ppc40x removal!

Removing 40x would help cleaning things a bit. For instance 40x is the 
last platform still having PTE_ATOMIC_UPDATES. So if we can remove 40x 
we can get rid of PTE_ATOMIC_UPDATES completely.


If no one objects, I can prepare a series to drop support for 40x 
completely.

Michael, any thought ?

I have no attachment to 40x, and I'd certainly be happy to have less
code in the tree, we struggle to keep even the modern platforms well
maintained.

At the same time I don't want to render anyone's hardware obsolete
unnecessarily. But if there's really no one using 40x then we should
remove it, it could well be broken already.

So I guess post a series to do the removal and we'll see if anyone
speaks up.

cheers

Ok, series sent out, see 
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=167757


While we are at it, can we also remove the 601 ? This one is also full 
of workarounds and diverges a bit from other 6xx.

I'm unable to find its end of life date, but it was on the market in 
1994, so I guess it must be outdated by more than 10-15 yr old now ?

ok. I see you have done it completely independently of my patchset.
Would be better if you can base it on the top of my 2 patches because
they are in conflict now and I need to also remove virtex 44x platform
also with alsa driver.

Thanks,
Michal

Ok, I found your first patch on another patchwork, it doesn't touch any 
file in arch/powerpc/

I sent a v2 series with your powerpc patch as patch 2/11

See https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=167766

There was just driver dependency on symbol which is removed by 2/2.
Let's see what you get from kbuild if any symbol is removed but still
used in drivers folder.

Nothing bad apparently, see build test at

There probably are still some people running Linux on 601 powermacs.

It could be marked as "BROKEN" for a year to find out for sure ;-)

Apparently there were only two or three models that are old enough to
have a 601 and new enough to run Linux with PCI and OF: 7200/8200
and 7500. These were sold for less than 18 months around 1996,
though one can still find them on eBay.

We shouldn't remove 40x completely. Just remove the Xilinx 405 stuff.

A. Wilcox said on IRC regarding 601 support in Adélie Linux:

"right now we are primarily targeting G3, though 603 should be supported.
601/601e support is planned to be added for 2.0 (next year)."

Didn't I give you my last 40x system ? :-) IBM still put 40x cores
inside POWER chips no ?

Good to know!

Are they still big-endian, or have they been corrupted by the LE frenzy,
too? ;)

According to Wikipedia (https://en.wikipedia.org/wiki/PowerPC_400), 405 
cores are used in modern equipments (how modern ?), however 403 has 
never reached the market.

Can we start removing 403 stuff ? That's not a lot, but still.

Does anybody knows anything about this ERRATUM 77 stuff ? Is that still 
an issue with all 405 cores or has this been fixed long time ago and can 
be removed ?

Christophe

Probably, but my desk is nearly as messy as yours so it's probably
buried under some even more obscure hardware :P

> IBM still put 40x cores inside POWER chips no ?

Oh yeah that's true. I guess most folks don't know that, or that they
run RHEL on them.

Is there a reason for not having those dts files in mainline then?
If nothing else, it would document what machines are still being
used with future kernels.

Also, if that's the only 405 based product that is still relevant with
a 5.7+ kernel, it may be useful to know at which point they
move to a 476 core and stop updating kernels on the old ones.

Nice to know :)

What's the plan then, do we still want to keep 40x in the kernel ?

If yes, is it ok to drop the oldies anyway as done in my series 
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=172630 ?

(Note that this series will conflict with my series on hugepages on 8xx 
due to the PTE_ATOMIC_UPDATES stuff. I can rebase the 40x modernisation 
series on top of the 8xx hugepages series if it is worth it)

I guess we keep it for now.

Perhaps we mark it BROKEN for a few releases and see if anyone
complains?

Yeah let's do it. I would love to get rid of that horrible
PPC405_ERR77() sprinkled all through our atomics.

Yeah if you can rebase that would be great.

I would like to get at least that xilinx patch to the tree to unblock
our changes on interrupt controller.

Thanks,
