* [PATCH 2/3 v2] Add initial iomega StorCenter board port.
From: Jon Loeliger @ 2008-01-08 22:07 UTC (permalink / raw)
To: linuxppc-dev
Use cuImage bootwrapper until U-Boot port is completed.
Derived heavily from Linkstation port.

Fixed Kconfig to select options rather than "depend on" them.
Fleshed out storcenter_restart() stub routines a bit.

Cleaned up config options by starting with ancient

arch/sparc{,64} should be easy if you have a cross compiler (though it
should work, Dave gets cranky if you break his tree :-)) Dave should just
take the patches if you do test compile them. Tell him I sent you :-)

The intention is that everyone only includes linux/of*.h (except for
linux/of*.h of course) at which point we should be able to remove the
includes of linux/of*.h from asm*/of*.h.

Some more unification should be possible over time, but that is much
harder.

* printk() does not work on UART1
From: mike zheng @ 2008-01-09 0:11 UTC (permalink / raw)
To: linuxppc-dev
Hi All,
I have one mpc8568 board using UART1 as the serial port. The OS is
Linux Kernel2.4. If I use the polling mode driver of
gen550_progress(), it works fine. However the printk() does not work
after the console_init(). Anyone know what shall I change in the
kernel to use UART1 as serial console? I assume the default is UART0,
but I don't know where the value is set. I changed the CONFIG_CMDLINE
to ttyS1, it does NOT work.
Thanks for your help,
Mike

Why do you this of_node_get(np) when you do not keep a reference to np in
this routine?

One of the unified bits I'd really like to see for the microblaze is the
interrupt handling stuff, i.e. irq_of_parse_and_map().

I have no idea what Scratchbox is, but when running gnu configure to
cross-compile something, you typically need to supply the following
switches:
--host=powerpc-linux --build=i686
and CC will have to point to your cross compiler (e.g. export
CC=powerpc-linux-gcc, or export CC=ppc_6xx-gcc, whatever your cross
compiler is called). Of course, the values of these switches will
depend on your setup, but this is what I use and I've built all sorts of
packages from source.

Ben

The macro define __FP_FRAC_ADD_4 is below. It can fix the carry bug.=20
But still exist a problem that r[0-2] and x[0-2] cannot be referred to
the same variable.
If r0 and x0 are the same variable, the comparison ( r0 < x0 ) will
always fail.
I don't know whether we need to fix this problem.

This of_node_get() should be in mpc512x_uart_of_assign() where the

You don't need these two (we are removing them) but move the .owner

* Use 2G RAM in 8548, vmalloc fail, adjust_total_lowmem
From: jay_chen @ 2008-01-09 4:06 UTC (permalink / raw)
To: linuxppc-embedded
Hello, all~~~
I am using a MCP8548 board with 2.6.14.5 kernel.
And I would like to upgrade memory from 512MB to 2048MB.
Finally, I realize this is not so easy as I think. I encounter several
problems. :~~
First, I change mem=512M to mem=2048M.
1. vmalloc fail problem
So, I change kernel config in "advanced setup"
Change "Set maximum low memory" from 0x30000000 to 0x80000000.
Change "Virtual address of kernel base" from 0xC0000000 to 0x60000000.
Change "Set custom user task size" from 0x80000000 to 0x60000000
Someone said that he could change "Virtual address of kernel base" to
0xA0000000 without problem.
Could I change it to 0x60000000? Any possible problem?
2.
In MMU_init( ), init.c
#ifdef CONFIG_FSL_BOOKE
/* Freescale Book-E parts expect lowmem to be mapped by fixed TLB
* entries, so we need to adjust lowmem to match the amount we can
map
* in the fixed entries */
adjust_total_lowmem();
#endif /* CONFIG_FSL_BOOKE */
In adjust_total_lowmem(), fsl_booke_mmu.c
It always limits the low memory to 768MB. (no matter we set mem=768MB or
mem=1024MB, or mem=2048MB)
__max_low_memory = max_low_mem = __cam0 + __cam1 + __cam2; (each TLB could
map up to 256MB)
My question is could I use more than 3 TLBs here? Such as 8 TLBs to map 2G
ram?
Or could I use e500v2 new feature, that is 1 TLB could map up to 4G? Any
reference code?
Any comment is welcom. Thanks a lot.
Jay Chen...

This violates the "one file, one value" rule of sysfs, but nobody
really takes that seriously, I guess. In any case, consider
documenting this in Documentation/ABI.

This statement will of course become dated/incorrect so I recommend
removing it.

I don't think this bit about early device tree access is correct. By
the time your code is reserving memory (from early_init_devtree(), I
think), RTAS has been instantiated and you are able to test for the
existence of /rtas/ibm,dump-kernel.

So I think these gymnastics are unneeded -- unless I'm
misunderstanding something, you should be able to determine very early
whether to reserve that memory.

Well, it seems to me that there's little reason to duplicate the s390
layout unless we can actually share code.
FWIW, I've been thinking about making a /sys/firmware/phyp hierarchy
which could contain much of the System P-specific functions (DLPAR,
lparcfg, other crud in /proc/ppc64)... seems suited to this
platform-specific dump mechanism.

No problem. I think you will find all these issues are applicable to
the mpc8560mds support that I based things off too. I'd rather do
a single patch for both boards to deal with these, rather than respin
the sbc8560 patches again and leave the mpc8560mds behind.
Assuming everyone else is OK with this approach.
Thanks,
Paul.

Yep it's early_init_devtree(), and yes it's fairly easy to access the
(flattened) device tree at that point.

In-Reply-To: <5c9cd53b0801081611ve59e9a8q6ae2fd227bfc0ed8@mail.gmail.com>
Hi All,
I have one mpc8568 board using UART1 as the serial port. The OS is
Linux Kernel2.4. If I use the polling mode driver of
gen550_progress(), it works fine. However the printk() does not work
after the console_init(). Anyone know what shall I change in the
kernel to use UART1 as serial console? I assume the default is UART0,
but I don't know where the value is set. I changed the CONFIG_CMDLINE
to ttyS1, it does NOT work.
Thanks for your help,
Mike

* printk() does not work on UART1
From: mike zheng @ 2008-01-09 5:11 UTC (permalink / raw)
To: linuxppc-embedded
In-Reply-To: <5c9cd53b0801081611ve59e9a8q6ae2fd227bfc0ed8@mail.gmail.com>
Hi All,
I have one mpc8568 board using UART1 as the serial port. The OS is
Linux Kernel2.4. If I use the polling mode driver of
gen550_progress(), it works fine. However the printk() does not work
after the console_init(). Anyone know what shall I change in the
kernel to use UART1 as serial console? I assume the default is UART0,
but I don't know where the value is set. I changed the CONFIG_CMDLINE
to ttyS1, it does NOT work.
Thanks for your help,
Mike

* [PATCH 0/5] Powerpc support for SBC8548 board
From: Paul Gortmaker @ 2008-01-09 5:18 UTC (permalink / raw)
To: linuxppc-dev
This is a repost of the SBC8548 patches, as requested, which contains the
dts-v1 patch and the pci exclude removal in addition to the original
three 8548 patches. These are layered on top of the SBC8560 patches
I'd sent yesterday (since they both go after the same Makefile/Kconfig etc).
The patches are as follows:
1) Add basic support for Wind River SBC8548 as powerpc
This adds in the basic platform support file -- closely matching that which
exists for the MPC8548CDS board.
2) Add device tree source for Wind River SBC8548 board
This also closely matches what exists for the MPC8548CDS platform. The big
difference here is that this board doesn't have physical access to PCI#2
and it doesn't have the CDS's bridges, i8259, peripherals, etc, so the dts
is overall quite a bit smaller. I've believe I've got all aliases and the
associated gianfar updates etc. that I'd somehow missed in the sbc8560 dts.
3) Add default .config file for Wind River SBC8548
This config gives basic serial console and ethernet support for doing an
NFS root setup. The SBC8548 has one PCI-X slot, and a short PCI-e slot,
so I've enabled PCI.
4) Convert device tree to be dts-v1 compatible
Tag all the values/resources normally in hex with 0x; convert items like
frequencies usually expressed in decimal to decimal; add the dts-v1 tag.
5) Remove PCI exclude device for sbc8548 and sbc8560
The exclude device doesn't need to filter out the PHB anymore, and since
that was all it was doing, it can go entirely.
Paul.

* [PATCH 1/5] sbc8548: Add basic support for Wind River SBC8548 as powerpc
From: Paul Gortmaker @ 2008-01-09 5:18 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Paul Gortmaker
In-Reply-To: <1199855910574-git-send-email-paul.gortmaker@windriver.com>
This adds the basic support for the Wind River SBC8548 board, implemented
as powerpc. It closely follows the implementation of the MPC8548CDS.
