Hi,
        I am= not willing to upgrade the uboot. Becuase it takes some time to
port th= e new uboot for my custom boad.
whether the current problem is related t= o uboot ? One more point, previously
i tried 2.6.21 with the same uboot(1.1.6) we got linux prompt but we fa= ce
some issue in the pci express in that version. so we plan to upgrade = the

I thought u-boot < 1.3 didn't unders= tand the flat tree at all.  In
which case you'll need a cu= boot zImage.

Hi,
         &n= bsp;Sorry i specify the wrong version, we r using 1.2.0. This uboot
was = taken from the BSP which was released by Freescale. Previously we testedlinux 2.6.21 kernel, we got linux prompt. For this we are using the same
uboot(1.2.0).
In that version we face some issues in the pci express= , at that time kumar
suggest to upgrade the kernel verison 2.6.23-rc3.Zhang did u suspect the problem is related to uboot?.

__log_buf is the actual buffer, log_buf points to the current in= sertion
point IIRC. It should be pretty obvious that you're looking at a dm= esg
buffer though, unless there's nothing in there for some reason.<= br>

Subject: Make mpc82xx use generic_calibrate_decr() To: Kumar Gala <galak@kerne= l.crashing.org>,     Tony Breeds

Message-ID: <20070913062201.GA24281@localhost.locald= omain>
Content-Type: text/plain; charset=3Dus-ascii

The on= ly difference between m82xx_calibrate_decr() and
generic_calibrate_decr() is that the former computes the timebase
fr= equency from the cpu node's bus-frequency property, instead of
direc= tly from the timebase-frequency property.

But there's no reason = the timebase-frequency shouldn't be correct on
82xx like everything else.  Certainly the 82xx bootwrapper in=
arch/powerpc/boot/cuboot-pq2.c should get it right.

Therefore, t= his patch removes mpc82xx_calibrate_decr(), using
generic_calibrate_decr= () instead.

I've comp= iled this, but no booted it, since I don't have any 82xx
hardware.&n= bsp; I'm hoping for an ack from someone who can test boot it.
