I've got a patch that adds 'raw' image support (originally written by
Scott Wood) which somewhat works for booting (but not entirely; I
haven't had time to dig into it properly yet).  It's not suitable to
go into mainline yet.  I'll try to get the patch out to my tree this
evening... actually I've been trying to get my tree pushed out all
today, but other things keep coming up.  

<several hours after I wrote the above>

Okay, I pushed my current patch set out to the master branch of my
linux-2.6-virtex tree.  Give it a whirl.  It's not perfect, but it
should be usable for booting.

Cheers,

 what is dmesg saying at this time?

 you might want to add some debug statements in the driver
 to see where it halts.. i guess the driver is not bound
 to the chip for some reason.

 your .config is right, the drivers are loaded
 but they are not bound to the chips as they are supposed to do.

 can you check that i2c_board_info structures / i2c_register_board_info
 are used by your platform?

Yes, we just showed ELDK 4.2 at the SPS/IPC/Drives trade show in
Nuremberg. OK, it's still beta since we wait for the final release of
Xenomai 2.4, but PPC and PPC64 beta is available for testers.

Two remarks:
- Please don't top post / full quote. See

- Please post ELDK related requests on the ELDK mailing list, see

I'm sorry, but I don't understand where you are having your problems.
Specifically, what error are you getting when your kernel fails to
compile?

As for the kernel version, I do not recommend using linux 2.4 any
more.  You should consider using a 2.6 kernel instead.  I've got some
documentation on the 2.6 kernel for virtex devices here:

ds1307 requires you to register i2c_board_info for it to probe properly.
Does your platform do so?

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

Hi

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 

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

After applying the at attached patch I got farther till
  CC      kernel/softirq.o
kernel/softirq.c: In function 'raise_softirq':
kernel/softirq.c:319: sorry, unimplemented: inlining failed in call 
to 'raise_softirq_irqoff': function body not available
kernel/softirq.c:342: sorry, unimplemented: called from here
make[2]: *** [kernel/softirq.o] Fehler 1

I thought that denx compiled images for the sequoia using 2.6.23. 
Do they only work after having applied the Xenomai patch? Because if I apply 
the Xenomai patch, the kernel compiles cleanly. In this case  I think it 
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.

Any clarifikation would be appreciated.

Best regards
