Re: Problem compiling sequoia using DENX kernel. Xenomai-patch required?

In message [ref] you wrote:

I tried with (tags DENX-v2.6.23.9, DENX-v.2.6.23, master) to build a kernel 
for the sequoia board.
I am using ELDK 4.1. I did a 
git checkout -b copy-master master
make ARCH=powerpc CROSS_COMPILE=ppc_4xx- CFLAGS=-g sequoia_defconfig 
make ARCH=powerpc CROSS_COMPILE=ppc_4xx- CFLAGS=-g zImage 

The ARCH=powerpc is the "interesting" part here.

First I stumbled about problem compiling arch/powerpc/platforms/44x/ppc4xx*.c
file with errors like
arch/powerpc/platforms/44x/ppc4xx-pci.c: In function 'ppc4xx_setup_pci':
arch/powerpc/platforms/44x/ppc4xx-pci.c:62: sorry, unimplemented: inlining 
failed in call to 'pci_cfg_out': function body not available
arch/powerpc/platforms/44x/ppc4xx-pci.c:98: sorry, unimplemented: called from 
here

There are many moving targets in the ARCH=powerpc hemisphere for 4xx
systems...

I thought that denx compiled images for the sequoia using 2.6.23. 

Yes, we do. But stable support is only available  with  the  arch/ppc
tree yet.

Do they only work after having applied the Xenomai patch? Because if I apply 

No.

the Xenomai patch, the kernel compiles cleanly. In this case  I think it 

That's just lucky coincidence...

would be nice to get somewhere a hint (or did I missed it somewhere) that 
this is a requirement. I lost quite a few hours as I wanted to first compile 
a "normal" kernel and afterwars apply the xenomai patch.

I'm afraid "normal" here still means arch/ppc  -  hopefully  for  not
long any more. Note: a matching Xenomai patch for arch/ppc will be in
Xenomai 2.4 when it comes out in a few days.
