This commit adds the setup code for booting Linux on AmigaOne G3SE (G3
only), AmigaOne XE and uA1 (G3/G4) desktop computers. These boards were
sold by Eyetech and are based on MAI Logic's Teron boards and its
Articia S northbridge.
The AmigaOne uses U-boot as firmware, which doesn't support a flattened
device tree yet. The northbridge has some design flaws, which makes it
necessary to use non cacheable memory for DMA operations
(CONFIG_NOT_COHERENT_CACHE) and to avoid setting the coherence (M) flag
for memory pages.

This device tree does not provide the correct CPU name, as various CPU
models and revisions are used in AmigaOnes. Also the PCI root node does
not contain a interrupt mapping property, as all boards have different
interrupt routing. However the kernel can do a 1:1 mapping of all PCI
interrupts, as only i8259 legacy interrupts are used.

This adds the bootwrapper for the cuImage target and a compatible property
check for "pnpPNP,501" to the generic serial console support code.
The default link address for the cuImage target is set to 0x800000. This
allows to boot the kernel with AmigaOS4's second level bootloader, which
always loads a uImage at 0x500000.

To: linuxppc-dev
CONFIG_CC_OPTIMIZE_FOR_SIZE is selected, because otherwise the kernel
wouldn't boot. The AmigaOne's U-boot firmware seems to have a problem
loading uImages bigger than 1.8 MB.

The AmigaOne uses the onboard VIA IDE controller in legacy mode (like the
Pegasos).

Why not just claim "ns16550" compatibility in the device tree node?

This patch needs to also be posted on the linux-ide mailing list.

I know you're just following the example of the PEGASOS workaround
immediately above; but the #defines are really ugly. I wonder if
there is there a cleaner way to manipulate the flags.

It was suggested that I should use PNP identifiers for all ISA devices, as
these are part of a real PCI2ISA bridge (when I sent the previous version
or these patches).

Ouch, I only sent it to the maintainer. I'll fix that.

AFAIK the via82cxxx driver doesn't make use of the pci_get_legacy_ide_irq
approach.

Okay, I just read that thread. Hmmm... I'm not fond of it but it is
an established convention and I cannot fault you for it.

show_cpuinfo() common code already prints the model. You can drop this hook.

If it doesn't noticeably slow down the boot then I would remove this line.
Otherwise looks okay to me.

Sounds to me like you need different device tree variants for each of
the AmigaOne boards. Do any of the boards have physical PCI slots?
If so, then the lack of an interrupt map will break them.

Experience has shown that trying to claim one board to be compatible
with another is too ambiguous. It is better to make the board level
compatible property have a single value specifying the exact board
model and have the platform support code include a list of supported
board models. Otherwise you end up with odd heuristic code to try and
differentiate between the models (for bug fixes and such).

For the flattened device tree, I think we've settled on the convention
that every node with an IRQ connection should have both the
interrupt-parent and interrupts properties. (ie. don't rely on the
parent node's interrupt-parent property.)

Drop device type in the flattened tree. There are a few places where
you still need to have it for Linux to work; but it Linux doesn't look
for it, then don't add it.

Can this PCI device be probed? Typically PCI devices don't get added
to the flattened device tree because PCI is a probeable bus.

If you put a 'serial-console:' label on the serial port node, then you
can use the simpler form of:
linux,stdout-path = &serial-console;

Don't do this; instead, have one multi-line asm statement (or better yet,
just use mfspr()/mtspr()/sync()/isync()).
GCC is perfectly free to trash your registers in between statements.

It doesn't seem any more likely to introduce a fault by specifying the
interrupt controller in one place than in many places.

We do the same thing with #address-cells and #size-cells for the same
reason. You can get away with leaving them out; but being explicit is
more clear.

That's different -- the defaults for #address-cells and #size-cells are
abitrary constants (2 and 1, respectively), not merely something that
was defined higher in the hierarchy.

Yes, all AmigaOne boards have physical PCI slots (at least 1). The different
interrupt routing wasn't a problem so far, as the firmware writes the IRQ number
to the interrupt line register of every PCI device.
Currently the kernel reads the IRQ number from this register, if there is no
interrupt mapping property. I know that it's not a good idea to rely on kernel
fallback behavior, but it makes a lot of things easier in this case.

Okay, I'll remove the "mai-logic,teron" entry. I have never seen a MAI Teron
in the wild, so I can't even tell if it uses a U-boot firmware.

Yes, the information in this node is probeable. Originally I planned to add
some child nodes to this node, as the PCI host bridge contains other PCI
functions (e.g. power management) which are not probeable. The host bridge
has an index register, which switches between the host bridge config space
and the config space of the other PCI functions. I don't know yet how this is
described correctly in a device tree, so I'll probably remove this node for now.

Yes, it can be probed. I thought it would be a good idea to include it,
because the IDE controller operates in legacy mode. I planned to specify the
two legacy interrupts in this node (as you can see), but the kernel didn't like
them.
Thanks!

I applied your patch for 2.6.29 but for 2.6.30 I would ask you to clean
up #ifdefs by using ide_pci_is_in_compatibility_mode() helper instead for
checking if IDE_HFLAG_FORCE_LEGACY_IRQS should be set.
[ Some time ago Pegasos got PCI quirk to put controller in the legacy mode
(arch/powerpc/platforms/chrp/pci.c) so it is OK to also remove Pegasos'
special case while at it. ]

Wouldn't it be better, if I clean this up now? (I have to resend my AmigaOne
platform patches anyway).

Okay, so the change shouldn't break IDE for Pegasos machines (I don't have
a Pegasos for testing).

Ah ? I use the trick of relying on the parent node regulary :-) Where

Also there's already some code around to properly flush & disable the
caches on those processors.

The code in the kernel that retreives the interrupt that way is clearly
marked as a fishy workaround for bogus firmwares :-)
But I'm not going to reject things based on that, it will work for
simple board using really only legacy interrupts like yours...

Sort-of. As long as it's really 8259 interrupts, I suppose it's
acceptable.

I disagree with Grant here. Especially in simple ISA cases like that,
there's really no point in bloating the device-tree.

Well, the kernel just didn't make use of them I'd say :-) But that can
probably be fixed with the appropriate hacks.

It is also entirely possible that I'm smoking something exotic.

Replacement patch instead of incremental one is also fine with me -- given
that it can wait for 2.6.30.

Yes but there may be some other platforms (not necessarily powerpc ones)
that may be affected (i.e. they can depend indirectly on IRQ auto-probing
during IDE probe) so cleanup patch needs to spend some time in linux-next.

Ouch! I searched through all assembler files in arch/powerpc/kernel/ for
such a function, but I have missed flush_disable_L1 in l2cr_6xx.S.
Thanks for the hint!

Yes, it can wait.
Although I would like to know from the powerpc maintainer, if my platform
patches could still go in 2.6.29, if I resend them in the next days? I guess it's
too late, right?

I think the VIA libata driver simply checks the progif register, too. I guess you
don't like the idea of a "#ifdef PPC32" or so around the
ide_pci_is_in_compatibility_mode() check?
Thanks!

Yes it is. I'll put them in -next after -rc2 or later, when we are happy
with them. That gives us a bit of time to do extra polishing.
Ben.

Good, then I'll send out a new patch for the IDE driver and the current one
can be reverted.

The following patchset fixes core IDE PCI code to always use
pci_get_legacy_ide_irq() and ide_pci_is_in_compatibility_mode():
http://lkml.org/lkml/2009/1/19/163
so via82cxxx specific solution is no longer necessary.
[ IOW I'll keep your previous patch and the #ifdef issue will
solve itself after the above patchset is merged. ]
Thanks,
Bart

Thanks a lot! That's much better than the simple fix I had planned.
