Appart from that, I'll have a quick look at the patch later today but at
first it looks good.

Or have a soc-level helper function for calling them for you; but yes.
And, no, we shouldn't have a vast array of individual initcalls
because the platform code shouldn't be that large. As much as
possible, multiple boards should be supported by the same platform
code. I argue that most boards using the same SoC should use the same
platform code. (see platforms/52xx/mpc5200_simple.c)
Individual calls has the added advantage that if a board port needs
those functions to *not* be called (for whatever reason) then it has
the ability to not call them.
It is for the same reason that the platform code is responsible for
calling of_platform_bus_probe() instead of it being an initcall; it
give the platform code control over the device registrations.

g.

Weird. pcibios_fixup_resources() should have printed things that I
didn't see in your log, which is why I asked...
I -think- your card is just asking too much, more than what we know how
to assign, but that doesn't explain why it used to work. I'll have to
dig a bit more.
You can assign more by changing the "ranges" property in the .dts, I
would expect the 44x PCI code I wrote to automatically adjust.

Ben.

The last time arch/ppc built for me (a few days ago), it got
535 warnings. I don't think anyone would notice one more.
Also, whoever doesn't yet know arch/ppc will be going away
has been living under a rock for the last two years.

I don't see anything exotic in here. This can be merged with one of
the other non-exotic mpc83xx board files. The dts parsing takes care
of the differences.

* [PATCH] sysdev,mv64x60: early console fix
From: Remi Machet @ 2008-04-21 21:02 UTC (permalink / raw)
To: Paul Mackerras, Dale Farnsworth; +Cc: linuxppc-dev
The MPSC driver and prpmc2800.dts have been modified to
use property 'cell-index' as the serial port number but
the early serial console driver for the mv64x60 has not
been modified to use this new property.

I don't understand that code.
What does the second bl __init_fpu_regiters do?
As I understand it, the first one is conditional on the presence
of an FPU (reasonable). But the secone one makes no sense.
Finally wouldn't it be simpler to initialize the FPU on all CPU

Becky pointed out that I had a copy/paste issue (duplicated the call to

The way other platforms do this is to hav SOC-specific
init code, and have board-specific initcalls call the
relevant SOC-specific setup.
Among other things that facilitates kernels that handle
multiple SOCs (if they're closely-enough related). That
may not be used by many distros (handhelds.org being at
least a partial exception), but it certainly helps cut
the number of configurations that need build-testing.

Nothing wrong with making stuff up as long as we do it sanely.

* [PATCH v7] [POWERPC] 85xx: Add support for relocatable kernel (and booting at non-zero)
From: Kumar Gala @ 2008-04-21 18:22 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
Added support to allow an 85xx kernel to be run from a non-zero physical
address (useful for cooperative asymmetric multiprocessing situations and
kdump). The support can be configured at compile time by setting
CONFIG_PAGE_OFFSET, CONFIG_KERNEL_START, and CONFIG_PHYSICAL_START as
desired.
Alternatively, the kernel build can set CONFIG_RELOCATABLE. Setting this
config option causes the kernel to determine at runtime the physical
addresses of CONFIG_PAGE_OFFSET and CONFIG_KERNEL_START. If
CONFIG_RELOCATABLE is set, then CONFIG_PHYSICAL_START has no meaning.
However, CONFIG_PHYSICAL_START will always be used to set the LOAD program
header physical address field in the resulting ELF image.
Currently we are limited to running at a physical address that is modulo
256M. This is due to how we map TLBs to cover lowmem. This should be
fixed to allow 64M or maybe even 16M alignment in the future. It is
considered an error to try and run a kernel at a non-aligned physical
address.
All the magic for this support is accomplished by proper initialization
of the kernel memory subsystem and use of ARCH_PFN_OFFSET.
The use of ARCH_PFN_OFFSET only affects normal memory and not IO mappings.
ioremap uses map_page and isn't affected by ARCH_PFN_OFFSET.
/dev/mem continues to allow access to any physical address in the system
regardless of how CONFIG_PHYSICAL_START is set.

Sorry I didn't get back to you earlier. Your best bet is to use
Xilinx's git tree and manually patch in the c67x00 driver from Peter
Korsgaard's driver.

The memory-constrained platform I had in mind was 8xx, which doesn't use
bitbanged MDIO. It might nice to keep the gpiolib bit separate to avoid
situations such as ep8248e where mdiobb would be the only thing requiring
a gpiolib binding, though -- but it shouldn't be two separate bitbang
drivers, just the existing bitbang driver plus some glue code that binds
it to gpiolib.

Ok. I'll have my grammar police review it and repost.

I'm not clear on why this is needed. I can see value in having the
PGD entry in place but the pte PAs would be changing all the time so I
don't see what benefit there is in keeping them in one page.
For normal kmap ptes we cover things in one PGD via:
#define PKMAP_BASE ((FIXADDR_BOOT_START - PAGE_SIZE*(LAST_PKMAP +
1)) & PMD_MASK)
The kmap_atomic ptes do NOT have a similar guarantee as they are
controlled via fixmap. However we do "pre-allocate" the PGD via
calling map_page() on all fixmap addresses.
