Sure, send 3/3 as well because this one depends on the cleanup patch, so
cannot be applied independently.

The previous stuff was odd .... but was it broken ?
It was done this way because the EMAC actually has more interrupts than
that which are routed to different UICs, and so doing a local map this
way allows to target multiple parents.
Cheers,
Ben.

No. This commit needs to be reverted. It breaks existing practices.
Pointing to yourself as a parent in order to provide a map is an old
trick and it should be supported.
I'll ask Linus to revert.

* Please revert commit dc9372808412edbc653a675a526c2ee6c0c14a91

Hi Linus !
Please, revert commit dc9372808412edbc653a675a526c2ee6c0c14a91
"of/irq: of_irq_find_parent: check for parent equal to child"
This breaks some powerpc platforms at least. The practice of having a
node provide an explicit "interrupt-parent" property pointing to itself
is an old trick that we've used in the past to allow a device-node to
have interrupts routed to different controllers.
In that case, the node also contains an interrupt-map, so the node is
its own parent, the interrupt resolution hits the map, which then can
route each individual interrupt to a different parent.
Cheers,
Ben.

Ah, nuts, yes that is broken then. Yes, please revert the commit and
Rob & I will come up with a better solution.
Rob, I think it can be done by explicitly checking for np ==
desc->interrupt_parent in of_irq_init() instead of relying on
of_irq_find_parent() returning NULL.

That "..." isn't very descriptive. What happens with 8192-byte pages?

Use braces on both sides of the if/else if it's needed on one side.

This should have set fbcr to index - column as well (after adjusting --
though really it's not a supported use case. We should only be seeing

Please use braces around multiline if/for bodies, even if they're
technically a single statement -- especially when you've got a dangling
else.

Why not just write priv->page_size = mtd->writesize / 2048 in the code
rather than the comment (it compiles to the same code)? Other than
because you were requested to remove priv->page_size, that is. :-)

buffer is a controller-wide resource, but you're setting it based on the
most-recently-probed NAND chip. It should be large enough to
accommodate the largest page size in use on any connected chip. Even if
all chips in the system have the same page size, you're introducing a
race if a previously-probed chip is already in use (the controller lock
is not held here).
Just allocate a buffer large enough for a 16K page size in the main init
function, and print an error in the tail if you encounter a larger page
size.

Clean up properly if you fail to allocate the buffer. This includes
freeing elbc_fcm_ctrl, setting fsl_lbc_ctrl_dev->nand to NULL, and
releasing fsl_elbc_nand_mutex.

Ben, I don't have anything particularly urgent for 3.2 and this seems
like it is well within the 3.2 window (defconfig updates usually come
later). Want to pick this up yourself, or do you want me to prep a

Well, in the canyonlands case, it appears that the interrupts went to
the same pic, so the simpler representation should be correct as
well. However, there certainly are boards where they go to multiple
pics, so we need this interrupt-map trick.

I'm working on 3.3 right now, so I'd rather you throw this in there, I
doesn't seem to be particularily urgent for 3.2 is it? (who actually
uses 4xx_defconfig ?)

Doesn't emac has something like 4 more interrupts that we simply haven't
been bothered wiring up (because we don't use them ?)

Leo, I have debugged this issue at my board just now, the reason of failure
is we only have one ep struct for ep0, so when talking about ep0, it always
pointers to udc->ep[0]. So even we initialize the current qh address for ep=
0in
at probe, it still can't get the ep0in's qh address through ep
structure, as ep0 is
always udc->ep[0].

It's mostly for linux-next / kisskb
There was a compiler error added to ndfc in upstream[1]. The change was in
linux-next but nothing currently builds that code. If we update
4xx_defconfig then linux-next will catch errors sooner.
So it's not urgent, but it doesn't hurt

The linux-next tree builds it. It would have caught a compile error
in the NDFC driver much earlier if we had it enabled in the defconfig.

Guys,
How are we handling this patchset since it touches drivers/mtd/nand?

Oops. I forgot the fact that we used a single ep structure to handle both =
IN and OUT ep0 because the gadget layer only knows about one ep0 structure.
I guess currently we have no other way out unless the gadget layer do honor=
ep0 with direction. IMHO, it is a limitation to current gadget APIs that =
each udc driver need to take too much care of the protocol related stuff on=
ep0.
Thanks,

* [PATCH] powerpc/40x: Add APM8018X SOC support
From: Tanmay Inamdar @ 2011-11-23 9:44 UTC (permalink / raw)
To: jwboyer; +Cc: linuxppc-dev, linux-kernel, Tanmay Inamdar
The AppliedMicro APM8018X embedded processor targets embedded applications that
require low power and a small footprint. It features a PowerPC 405 processor
core built in a 65nm low-power CMOS process with a five-stage pipeline executing
up to one instruction per cycle. The family has 128-kbytes of on-chip memory,
a 128-bit local bus and on-chip DDR2 SDRAM controller with 16-bit interface.
Features:
*CPU speed (frequency): up to 600 MHz
*Five-stage pipeline, executes up to one instruction per cycle
*16 KB-I/16 KB-D L1 caches, two-way set-associative
*128 KB on-chip memory
*128-bit processor local bus (PLB)
*Separate 128-bit read and 128-bit write data bus
*Up to 6.4 GBps of peak on-chip bandwidth at 200 MHz
*On-chip DDR2 SDRAM controller with 16-bit interface
*Support for one rank of DDR2 SDRAM up to 512 MB
*One Gen 1 single-lane PCI Express interface
*One Gen 1 single lane miniPCIe interface
*Configurable as root or endpoint
*One SATA controller operating at up to 3.0 Gbps with integrated SerDes
*Two Ethernet 10/100/1000 Mbps, full-duplex MACs (RGMII/TMII/MII)
*TCP/IP acceleration hardware, QoS, and jumbo frame support
*IEEE 1588 V1 and V2 support
*On-chip IPsec acceleration with header/trailer processing
*Supports DES, 3DES, and AES encryption
*Operates at 1.5/12/480 Mbps bus speeds

This is only relevant for this SOC isn't it? If so, it might be better
to add it to arch/powerpc/platforms/40x/Kconfig.
The help line can be dropped (there's no prompt, so the help won't be
user visible).
Some people would suggest to use
def_bool n
here. (I don't really care.)

Why is this "default y"? All other "selectors" of PPC40x_SIMPLE default
to n.

There was recently some powerpc related discussion on using "select" on
symbols that are themselves user selectable (see
https://lkml.org/lkml/2011/11/9/426 ). But other symbols already select
this symbol so this is not specific to this patch.

Since you're selecting it here it's good that you made
UART_16550_WORD_ADDRESSABLE hidden (as it has no prompt). But perhaps
you could even drop it and in the code just test for CONFIG_APM8018X. Or
are you expecting more users of UART_16550_WORD_ADDRESSABLE?

Are you using kvm-tool to do this? QEMU can already hot-plug ports
and virtio-console (virtio-serial) devices.

I don't really understand why. "fix locking of vtermno" adds locks in
init_port_console(), which is called from add_port(), which should be
serialised due to port additions being on work items on the same
workqueue. I don't see a race here.

I don't see any difference in my testing with and without these
patches.
This is how I tested with qemu:
./x86_64-softmmu/qemu-system-x86_64 -m 512 -smp 2 -chardev
socket,path=/tmp/foo,server,nowait,id=foo -chardev
socket,path=/tmp/bar,server,nowait,id=bar -device virtio-serial
-device virtconsole,chardev=foo,nr=4 -device
virtconsole,chardev=bar,nr=3 -net none -kernel
/home/amit/src/linux/arch/x86/boot/bzImage -append 'root=/dev/sda1
console=tty0 console=ttyS0' -initrd /tmp/initramfs.img
/guests/f14-nolvm.qcow2 -enable-kvm -snapshot
With this setup, with and without patches, I can spawn two consoles
via:
/sbin/agetty /dev/hvc0 9600 vt100
/sbin/agetty /dev/hvc1 9600 vt100
(Strange thing is, the second one gives a 'password incorrect' error
on login attempts, while the first one logs in fine. I do remember
testing multiple consoles just fine a year and a half back, so no idea
why this isn't behaving as expected -- but it mostly looks like a
userspace issue rather than kernel one.)
As mentioned earlier, I've not looked at the hvc code, but given my
testing results, I'd like to first understand what you're seeing and
what your environment is.
