OK.

Yeah, it has always been a bit ambiguous.

No worries.

* [PATCH 1/4] powerpc: mv64x60 - Use early_* PCI accessors for hotswap reg
From: Mark A. Greer @ 2008-01-14 22:51 UTC (permalink / raw)
To: linuxppc-dev
From: Mark A. Greer <mgreer@mvista.com>
The mv64x60 Hotswap register is on the first hose of the mv64x60
hostbridge. To access it, manually find the hose structure and
use the early_* PCI accessor routines because the hostbridge is
normally hidden.

It is not 8xx centric; it is a compatibility layer for old,
non-device-tree aware u-boots (regardless of what chip you're using).

Search for "device tree" in u-boot's README.

Yes, but then either the order in errtable[] wouldn't match the order in
the header file, or the error type grouping would be broken.
If we want to maintain such a grouping, we should probably leave some
number space between the groups.

"pointer to a string" could be interpreted as "char *", not "char **".
I'll fix the others; thanks for pointing them out.

Hmm, some old code I did to make Linux boot from the former ppc stuff
works fine to the loading and booting @ 0x4000000 - this step is pretty
much fine, I think.

Ah.
This explains eveything then.. there _is_ a magic image and I haven't
been booting it !
Typical.
I'll give the 8xx-centric ucImage a go.

Ah OK, I see so the procedure would be to dtc a dts representing the
Adder.
Download both this and a uImage ... and then as you say pass the address
of the blob to Linux via U-Boot.
It occurs to me that this type of procedure should really be added to
the Documentation...
There's no mention of it in the Linux documentation, nor in the u-boot
documentation and uncle Google was not informative for the types of
searches I was doing....
Somebody - possibly even me, since I'm mentioning it - should write a
copule of paragraphs on booting a ucImage with a of-blob and add it to
both U-Boot and Linux..
> If you're not comfortable with the device tree stuff, I recommend just

Indeed.
Thanks for the response Scott. I'll try out the ucImage and all going
well with that will try the three parameter Linux + blob based on
the .dts, hopefully over the next three or four days....
If I'm unlucky I might bug you again... and if I have more luck, I'll do
a follow up on the list.
Happy Monday !

Bryan

These macros can reference their arg more than once and are hence
dangerous. What does PREV_PHASE(foo++) do to foo?
And, in general: do not implement in cpp that which could have been
implemented in C.

Microscopic note: kernel code tends to do

if more than one is being tested.

The compiler treats 0xNNN constants as unsigned so this works OK. I'd have
put a UL on the end of the constant to be sure ;)

Is this the sort of thing which should be controlled at compile-time? I'd
have thought that a runtime control would be more appropriate (a sysfs knob
or a module parameter). Or just work it out automagically?

eek. What are we doing here, casting a 32-bit quantity to a kernel pointer?
a) Seems to rule out ever using this driver on a 64-bit system
b) It's generally suspicious and indicates that some rethinking is needed.

Again, is it appropriate that this behaviour be determined at compile-time?
This is very user- and packager- and distributor-unfriendly.

What has been confusing me is that I am unable to reproduce the
problem in real mode. I can only reproduce the problem in virtual
mode. This leads me to believe, perhaps mistakenly, that the hardware
is implemented okay. OTOH, neither can I see anything wrong with the
software.

I am currently testing code on the ML403 evaluation board. I used the
Base System Builder in EDK to create the hardware design and DDR SDRAM
is being used as the main RAM starting at address 0x00000000 and also
with OCM BRAM mapped at the very end of the address space (so that
0xfffffffc can contain code to execute on startup).
I am now trying to experiment with the hardware and see if I can find
a hardware reference design. I will let you know what I figure out.

Which matches the defines in include/configs/warp.h:
#define CFG_EBC_PB1AP 0x018003c0
#define CFG_EBC_PB1CR (CFG_NAND_ADDR | 0x1c000)
It also matches the defines in sequoia.h except that we are on CS1 and
the sequoia is on CS3.

And the EBC0_BxCR & EBC0BxAP registers for the CS where the NAND is connected?
How are they configured?

Right, nothing on recent systems is using the map files. This patch
should not be needed.
The plan is to deprecate the creation of these files in depmod.

I posted something in one of the i2c device tree threads a while ago:
http://ozlabs.org/pipermail/linuxppc-dev/2007-May/036353.html
Basically, you just have a node that is both an i2c device and an i2c
controller, and the mux driver binds to it and registers the subordinate
buses as new i2c controllers.

If you are using the secretlab.ca or git.xilinx.com trees, then you
should *not* follow the normal BSP generation process. You need to
generate the BSP in a dummy location and then copy only the
xparameters_*.h file over the appropriate one in
arch/ppc/platforms/4xx/xparameters and make menuconfig.

Hi, I was reading this post and a question came to my mind.
When I try to compile, did I have to copy the EDK driver folder to my Xilinx

Ah, right. I see it now, there's modules.isapnpmap,
modules.ieee1394map, modules.pcimap etc. but no modules.i2cmap.
However, there is modules.alias which contains the i2c aliases for all
device types (including one ieee1394 and many pci aliases) which seems
somewhat redundant with the modules.*map files.

I am under the impression that modules.*map are the old way to get
automatic driver loading and aliases are the new way to do the same.
But maybe that's just me.

In the EBC0_CFG register we set the RTC (Ready Timeout Count) to 0 and
the sequoia uses 7. Also we set the EMS (External Master Size) to none
and the sequoia sets it to 8 bit.
This is in uboot, the dts are basically the same.

I've just looked it up again (I had to do a similar thing for Zorro bus
support). Module-init-tools (depmod) also creates the modules.*map files,
which are used to map from device IDs to module names. I think these are used
by udev to load the appropriate module when a device with a specific device ID
pops up in sysfs.

Yes, it's also still not 100% clear to me when `i2c:Nadm1032' is used, and when
modules.i2cmap would be used...

I thought that the module aliases were generated by
scripts/mod/modpost? As a matter of fact, I did not apply Jon's patch
to module-init-tools, and "modinfo" shows me module aliases properly
for i2c drivers that call MODULE_DEVICE_TABLE():

The way it was implemented back then did not make sense. As it was not
clear whether we would implement something different or nothing at all,
I decided to plain remove it. Now that it seems that we want to
implement it differently, I'm looking into it again.

* [DTC PATCH] libfdt: Add ft_get_next_node(), ft_get_next_prop(), and ft_getprop_offset().
From: Scott Wood @ 2008-01-14 16:30 UTC (permalink / raw)
To: jdl; +Cc: linuxppc-dev
ft_get_next_node() enumerates children of a given node.
ft_get_next_prop() enumerates propreties of a given node.
ft_getprop_offset() is like ft_getprop(), but takes a property offset rather
than a node offset and property name; it is primarily intended for use
with ft_get_next_prop().
