* [POWERPC v2] powerpc: Add -mno-spe for ARCH=powerpc builds
From: Kumar Gala @ 2007-10-19 13:00 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Paul Mackerras
In-Reply-To: <E1IirI4-0004Ch-3P@jdl.com>
Newer GCC's are capable of autovectorization for ISA extensions like
AltiVec and SPE. If we happen to build with one of those compilers we
will get SPE instructions in random kernel code. Today we only allow
basic interger code in the kernel and FP, AltiVec, or SPE in special
explicit locations that have handled the proper saving and restoring of
the register state (since on uniprocessor we lazy context switch the
register state for FP, AltiVec, and SPE).
-mno-spe disables the compiler for automatically generating SPE
instructions without our knowledge.

Hopefully this is up to Paul's double standard :)

My patch got rid of this xtime_lock stuff -- but this was in a different

Wait, how this is related to the hrtimer's event handlers not being able
to call account_process_time() from arch/powerpc/kernel/time.c instead of

I'm not aware of the QE being present on any 64-bit PowerPC. However,
porting the entire driver to a 64-bit platform is an exercise in itself
as many other things would need tweaking the QE hardware itself. But
that's an orthogonal issue. For now I just want to fix that warning.

Agreed, but again, I'm not trying to fix the entire driver or to port it
to a different architecture.
For the current situation, 32-bit QE, 32-bit PowerPC, do you find the
patch acceptable?

Basically anything that deals with the flattened device tee should
include asm/prom.h. This may change in the future, but that will be my
problem. linux/of.h should be included for dealing with the unflattened

Yes, I've seen that. It means something went wrong with the setup and
caused the sysace to reload the FPGA. Is the systemace base address
and bus width set correctly?

[Unrelated to the patch.
I've tried to erase first (hrcw) sector, everything passes fine, but
`md fe000000` still gives data back. Probably some hardware magic used
to prevent this? ;-)

Good idea.

Here it is:
bootcmd=run ramargs;cp.b fff00000 400000 2000;bootm ff800000 ffa00000 400000
I.e.
0xFF800000 - kernel
0xFFA00000 - ramdisk
0xFFF00000 - dtb, one sector
Reworked patch (lbus+flash) follow, using this stock partitions map:
0x00000000-0x00020000 : "hrcw" <- 128 kB
0x01f80000-0x02000000 : "u-boot" <- 512 kB
0x00020000-0x01800000 : "rootfs" <- 24448 kB
0x01800000-0x01a00000 : "kernel" <- 2048 kB
0x01a00000-0x01f00000 : "ramdisk" <- 5120 kB
0x01f00000-0x01f20000 : "dtb" <- 128 kB
0x01f20000-0x01f80000 : "spare" <- 384 kB
I'm not sure about "ramdisk" partition though, maybe concatenate
kernel+ramdisk to use with initramfs kernels instead?

1. debootstrap with the --foreign

booting-without-of.txt has some information about describing the controller.
Scott Wood made an attempt at defining a device binding for I2C
devices, but it has not been merged into booting-without-of.txt yet.
I've copied what he wrote below. I would add to his definition the
following:
- If compatible is missing, driver should *not* fall back to the device name.
- 'compatible' list should include the exact device in the form "<mfg>,<part>"
Cheers,
g.
Here's the thread and an excerpt from Scott's original post:
http://patchwork.ozlabs.org/linuxppc/patch?id=11223
+ e2) I2C Devices
+
+ Required properties :
+
+ - reg : Unshifted 7-bit I2C address for the device
+
+ Recommended properties :
+
+ - compatible : The name of the Linux device driver that
+ handles this device. If unspecified, the name of the
+ node will be used.
+ - interrupts : <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and level
+ information for the interrupt. This should be encoded based on
+ the information in section 2) depending on the type of interrupt
+ controller you have.
+ - interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+
+ Example :
+
+ rtc@68 {
+ device_type = "rtc";
+ compatible = "ds1374";
+ reg = <68>;
+ interrupts = <13 8>;
+ interrupt-parent = <700>;

This series of patches enables the EMAC driver for the Ebony, Walnut, and

I'll put these and a few other patches that have been sent to me into my git

* [patch 2/4] 4xx: Fix timebase clock selection on Walnut
From: Josh Boyer @ 2007-10-19 14:53 UTC (permalink / raw)
To: linuxppc-dev
In-Reply-To: <20071019145307.978880000@linux.vnet.ibm.com>
The current bootwrapper fails to set the timebase clock to the CPU clock
which causes the time to increment incorrectly. This fixes it by using the
correct #define for the CPC0_CR1 register.

* [patch 4/4] 4xx: Enable EMAC on Bamboo board
From: Josh Boyer @ 2007-10-19 14:53 UTC (permalink / raw)
To: linuxppc-dev
In-Reply-To: <20071019145307.978880000@linux.vnet.ibm.com>
Fix some device tree omissions that prevented the new EMAC driver from
setting up ethernet on the Bamboo board correctly and update the Bamboo
defconfig.

* [patch 3/4] 4xx: Enable EMAC for PPC405 Walnut board
From: Josh Boyer @ 2007-10-19 14:53 UTC (permalink / raw)
To: linuxppc-dev
In-Reply-To: <20071019145307.978880000@linux.vnet.ibm.com>
This patch enables the ibm_newemac driver for the Walnut board. It fixes the
device tree for the walnut board to order the MAL interrupts correctly and
adds the local-mac-address property to the EMAC node. The bootwrapper is also
updated to extract the MAC address from the OpenBIOS offset where it is stored.
