* Help with device tree binding for SMC serial
From: Rune Torgersen @ 2008-01-09 19:18 UTC (permalink / raw)
To: linuxppc-dev
Hi
We're trying to get a SMC serial port on a8280 to work.
I cannot find any ecxamples on the binding, so we've tried to make one.
is this anywhere close to workable?
serial@11a80 {
device_type =3D "serial";
compatible =3D "fsl,mpc8280-smc-uart",
"fsl,cpm2-smc-uart";
reg =3D <11a80 10 87fc 2>;
interrupts =3D <4 8>;
interrupt-parent =3D <&PIC>;
fsl,cpm-brg =3D <7>;
fsl,cpm-command =3D <01000000>;
};

* Trying 10/HALF
From: Siva Prasad @ 2008-01-09 19:35 UTC (permalink / raw)
To: linuxppc-dev, linuxppc-embedded
[-- Attachment #1: Type: text/plain, Size: 475 bytes --]
Hi,
After booting, my MPC8641 based board keeps printing "Trying 10/HALF"
for ever. I am unable to use the Ethernet, even though there are
interrupts occuring. Based on /proc/interrupts, both tx and rx interrupt
count is increasing, and zero count for enet_error interrupt.
I think this is coming from drivers/net/phy/phy.c during
autonegotiation. However, I am not sure how to take care of this.
Appreciate some pointers.
Thanks
Siva

Yeah I agree with that as well.
I'm thinking I'll add something like:
if (addr < total_lowmem)
reserve_bootmem(lmb.reserved.region[i].base,
lmb_size_bytes(&lmb.reserved,
i));
+ else if (lmb.reserved.region[i].base > total_lowmem) {
+ unsigned long adjusted_size;
+// adjusted_size = xxx;
need to figure out the math here.
+ reserve_bootmem(lmb.reserved.region[i].base,
+ adjusted_size);
+ }
that should solve the problem.

The current binding has the actual parameter ram block as the second reg
property, not the two-byte pointer. If your firmware doesn't initialize
the pointer, you'll have to do it in platform code.

cpm-command should be <1d000000> for SMC1.
Otherwise, it looks OK.

We don't want to allocate ring buffers for network interfaces that are never
opened, especially given the small amount of memory on some boards that use
this driver.
Instead, we should probably not be calling napi_enable() until the link is
up and init_bds() has been called.

I know there are already ifdefs of this sort, and that multiplatform
cpm1/cpm2 is very unlikely to ever happen, but can we try to avoid
introducing more such ifdefs?
We can have both match entries present at the same time.

This is already defined in asm-powerpc/commproc.h, and thus will cause a
duplicate definition when building for 8xx. Please add this definition to
asm-powerpc/cpm2.h.

Please define 0x20 as SCC_GBL (Snooping Enabled) in cpm2.h, and
conditionalize this on #ifndef CONFIG_NOT_COHERENT_CACHE.
You can remove the comment; it's really necessary, not just "seems" so. :-)

Ah, possibly. Did you try doing a 'select USB_ARCH_HAS_OHCI' in the
config 440EP section of arch/powerpc/platforms/44x/Kconfig?
I'm just trying to save you some trouble. There's nothing actually
wrong with your patch now, other than it has to be sent to the right
maintainer.

* [PATCH 5/5] Warp Base Platform - cputable

In-Reply-To: <47852C41.8000506@pikatech.com>
I think I sent this, but I will include it here for completeness.
It adds the 440EP Rev C to the cputable.

Wouldn't it just be total_lowmem - lmb.reserved.region[i].base?

Hi
I switched "Xilinx uartlite serieal port support" and "Support for console on Xilinxuartlite serialport" on and "8250/16550 and compatible serial support" off, in the kernel config.
Then I removed the things I added in the xparameters.h and compiled successfully.
But I have yet a few Questions:
- What would you recommend to use? UART-Lite or a 16550 serial port. Can I get a console running on the RS232 Port of the Board with both possibilities?
- Can you recommend anything for my next steps to get an running linux (rootfs usw.)? So far I oriented myself on the Klingauf page, but I think it is perhaps not the best one because its too old and some things will probably not work the way he did it anymore.
Greez & Thanks

Which, of course means that the "result" temporary isn't needed either.

Right, the modalias needs to be the same as the driver name, not the
module name, so you should change it to mmc_spi as well.
For loading the module it would not make a difference because - and _
are treated the same by the module loader, but the device only
gets associated with the driver when it matches exactly.

Ok. keeping the code itself in the mpc52xx_psc_spi driver is fine as long
as it's relatively small. Other of_platform_drivers for SPI will just
have to it the same way.

if you don't need to change the baud rate at runtime then use the uartlite.
Console works on both.

Use either ELDK or buildroot. Personally, I'd like to be using
OpenEmbedded, but I haven't been successful with that yet.

Ok we're now using
serial@11a80 {
device_type =3D "serial";
compatible =3D "fsl,mpc8280-smc-uart",
"fsl,cpm2-smc-uart";
reg =3D <11a80 10 0 40>; // <base_address length
parameter_ram_address length>
interrupts =3D <4 8>; // Interrupt from table 4.3
of mpc8280rm, interrupt is level or edge
interrupt-parent =3D <&PIC>;
fsl,cpm-brg =3D <7>;
fsl,cpm-command =3D <1d000000>; // Page and Sub-block code
of the CPCR
};
Right now we're trying to just get a kernel to give us some serial
output, so we can continue the porting job.
We're unsig a cuImage (using the pq2fads code right now).
Now our problem is that the serial port is spitting out 0x0a's as fast
as it can.
Seems to be repeadtin the linefeed at the end of "Uncompressing Kernel
Image ... OK"

Don't forget to exclude the SMC parameter RAM from the muram data area
in /soc/cpm/muram/data/reg. If you have an older device tree binding
that has no /soc/cpm/muram node, but instead has two resources in
/soc/cpm/reg, you need to move to head-of-tree to get this to work.

Did that, now we get e checkstop resert. Time to hook up the
BDI-2000....
Is there a way to have the bootwrapper use the u-boot serial for a while
(like a early srial port) for debugging?

If you mean calling into u-boot for a console, no, there's no code for that.
What do your cpm and muram nodes look like?

It's in "production" with 256MB of RAM? Err. Sure as the dump progresses
more RAM will be freed, but that's hardly production. I think Nathan's
right, any sysadmin who wants predictability will probably double reboot
anyway.

Yeah that's a good question. Even if the hot-onlining works, there's
still kernel data structures allocated at boot which want to be
node-local. So the end result will be != a "production" boot.

AFAICT you don't need to get at RTAS, you just need to look at the
device tree to see if the property is present, and that is trivial.
You probably just need to add a check in early_init_dt_scan_rtas() which
sets a flag for the PHYP dump stuff, or add your own scan routine if you
need.
