* [PATCH] ppc32 8xx: fix m8xx_ide_init() #ifdef
From: Marcelo Tosatti @ 2005-08-23 20:20 UTC (permalink / raw)
To: akpm; +Cc: linux-ppc-embedded
Be more precise on deciding whether to call m8xx_ide_init() at
m8xx_setup.c:platform_init().
Compilation fails if CONFIG_BLK_DEV_IDE is defined but
CONFIG_BLK_DEV_MPC8xx_IDE isnt.
Please apply.

* [PATCH] Allow ns16550.c to get base baud from rs_table instead of BAUD_BASE
From: Grant Likely @ 2005-08-23 22:07 UTC (permalink / raw)
To: linux-ppc-embedded
Modifies serial_init to get base baud rate from the rs_table entry instead
of BAUD_BASE. Will default back to BAUD_BASE if base_baud is not set.
This patch eliminates duplication between the SERIAL_PORT_DFNS macro and
BAUD_BASE. Without the patch, if a port set the baud rate in
SERIAL_PORT_DFNS, but did not update BASE_BAUD, the BASE_BAUD value
would still be used.
Rather; serial_init() should look first in SERIAL_PORT_DFNS and use
BASE_BAUD as a backup.

Perhaps... but it's not the _second_ machine check. We already take 33
of them, and recover, while the i8042 driver is poking for hardware. We
also tend to survive a few while the 8250 driver is poking... but not
all of them.
Some timing issue with recovering and then causing another machine check
in quick succession?

* [PATCH] ppc32: Only enable L2 prefetching if the L2 cache is enabled on 744x/745x
From: Kumar Gala @ 2005-08-23 23:32 UTC (permalink / raw)
To: Benjamin Herrenschmidt; +Cc: linuxppc-dev
(Ben, this needs to be tested before sending upstream, but I think it
looks good)
We run into problems if we blindly enable L2 prefetching with out checking
that the L2 cache is actually enabled. Additionaly, if we disable the L2
cache we need to ensure that we disable L2 prefetching.

Dear Ricardo and Wolfgang,
Very thanks for your kindly support.
I am sorry I made a mistake.
Before you mount /dev/mtdblock4, you have to use mke2fs to format it.
Now I think my MTD function is almost ready, except write.
When I run "dd if=/dev/mtd1 of=kernel.img", it's OK.
But when I run "dd if=kernel.img of=/dev/mtd1", it's failed. No error
message printed, and the process time is shortly, cause Bad CRC.
Thanks,
Johnson Cheng

Well, do you have an mtdblock4 entry in /dev?
Also, you should specify your filesystem type to mount, like in:
mount -t jffs2 /dev/mtdblock4 /mnt
BTW, -t jffs2 is just an example.

Umh, I just recognized the 720101 isn't from NEC's hub series, but it's
the host controller itself (720110 would have been a hub also...)! My
bad.
So I'm afraid our problems are unrelated.
>From the logs you sent I'd say your problem starts right here:
ohci_hcd 0000:00:0e.0: request interrupt 17 failed
You should check your PCI interrupt routing, trace INTA from the device,
it's IDSEL, etc. Look at /usr/src/linux/arch/ppc/platforms/sandpoint.c
and lspci -vvv.
But I'm not familiar with the sandpoint, so that's it for me...

But here you are missing to pass the information which ethernet interface to use.

But there are two intefaces. Which one should the kernel use?
Just fix your bootargs.

You're trying to insert a module that depends on another
module/functionality in the kernel but which you did not insert or
compile in the kernel.

Before doing a write to /dev/mtd1 try running
~# eraseall /dev/mtd1
(eraseall is from the mtd-utils package.)

At compile time the compiler assumed these symbols would be defined externally, either by the kernel
or by another module loaded prior to hello.o. The error message says that these symbols are not
exported by the kernel (or any currently loaded modules) prior to running "insmod hello.o".
Either:
1. You need to insmod another module first (or use "modprobe hello" which may do this automatically)
2. The module defining these symbols has not used the EXPORT_SYMBOL() macro to make them exported.
3. These symbols are not defined in either the kernel or any modules.

* RPXClassic Help
From: Travis B. Sawyer @ 2005-08-24 12:12 UTC (permalink / raw)
To: linuxppc-embedded
Greetings:
I got my hands on a couple of RPXClassic (CLLF) boards gratis
and am planning on putting them to some use with my model
railroad (overkill, but its fun!).
I have them running Das U-Boot git as of ~ 16August2005.
I'm attempting to use a kernel.org 2.4.30 kernel. (With
i2c-2.9.0 patches)
After pushing the bd_t struct into rpxclassic.h, the board
boots linux well, mounts the nfs root properly, things are
good.
I would like to get a pcmcia flash disk working. It is id'ed
by Das U-Boot:
PCMCIA:SunDisk SDP 5/3 0.6

Type: Removable Hard Disk
Capacity: 61.2 MB = 0.0 GB (125440 x 512)
After enabling pcmcia, 8xx pccard, ide, et al (and some debug printk's)
I get the following output from the kernel:
Uniform Multi-Platform E-IDE driver Revision: 7.00beta4-2.4

I use the PCMCIA card services at sourceforge instead of the built in
support. They work very well including ATA/IDE.
