Hi,all:
This is my first time to post on this maillist,I got a problem that ping can
not work and I am wondering if it is because of my mismatch of linux kernel
and DTC compiler version.
I am using mpc8544ds_bsp provided by freescale.
I used uboot2009.08 to boot my board successfully.
At first, I

Subject: Ping does not work on my MPC8544 board, using linux2.6.23
why linux-2.6.31 doesnot provide a config file like
mpc8544_ds_defconfig?
Because it is covered by common defconfig mpc85xx_defconfig.

Probably not -- 2.6.23 is very old, and I think newer dtcs only support the
newer dts syntax.
Another question is that I found linux2.6.31 does not support
board mpc8544ds,
It should.

It appears that we wrongly calculate dev_base for type1 config cycles.
The thing is: we shouldn't subtract hose-first_busno because PCI core
sets PCI primary, secondary and subordinate bus numbers, and PCIe
controller actually takes the registers into account. So we should use
just bus-number.

Hi,
Also no NUMA is going to hurt Cell too. I think we should leave that in.
It was never enabled in the ppc64 defconfig :) I'm happy to turn it on though.

Josh,
Sorry for my ignorance that I did not copy you first. From now on I

Should I send new patch with what is tested with this change or is it

Yes, badly designed hardware deserves ugly hacks in the platform

At the moment when we EOI an interrupt we set the CPPR back to 0xFF
regardless of its previous value. This could lead to problems if we
take an interrupt with a priority of 5, but before EOIing it we get
an IPI which has a priority of 4. The problem is that at the moment

* Exports mpc85xx_cache_sram_alloc()/free() APIs
