EP405 linker error.

Hi all,

Here is what I did before:
 cd /opt
 bk clone bk://ppc.bkbits.net/linuxppc_2_4_devel linuxppc_2_4_devel
 cd linuxppc_2_4_devel
 bk -r get -q
 bk edit Makefile
 vi Makefile
 	|-> ARCH := ppc
 	|-> CROSS_COMPILE = ppc_4xx-
 	|-> AFLAGS := -D__ASSEMBLY__ $(CPPFLAGS) -Wa,-m405
 	`-> kbuild_2_4_nostdinc	:= -nostdinc $(shell $(CC) -print-search-dirs | sed -ne 's/install: \(.*\)/-I \1include/gp')
 		`-> this one is to avoid the "stdarg.h: not found" stuff in 'make dep'. This will include the ELDK headers.
 make ep405_config
 	`-> I have the EP405 board, o wonder ;-)
 make menuconfig
 	|-> Activate Unix98 PTY and /dev/pts support
 	|-> Deactivate PCI support (gave me errors)
 	`-> Deactivate I2C support (same story)
 make dep
 make zImage

And this last step gives me the following error:
 ppc_4xx-ld -T arch/ppc/vmlinux.lds -Ttext 0xc0000000 -Bstatic arch/ppc/kernel/head_4xx.o init/main.o init/version.o init/do_mounts.o \

So it's a link problem at the final linkage to vmlinux. Does anybody have an idea how I can solve this one? I haven't found anything on Google.

Thanks in advance.

Most probably you have disabled PCI support.

These missing functions are defined in arch/ppc/kernel/pci.c (funny macros
at the file end)

Correct, I disabled PCI because if I enable PCI, I got his error:

I didn't know that there was an ATI RADEON on this EP405 ;-) How come that it seeks for that? Wrong .config?

The check is done in runtime not when you compile and you can have the
card  on any system with a pci bus.

For now just remove the line and everything will be OK since you did not
have the card.

I commented out line 693 in drivers/pci/quirks.c and now it compiles. Thanks for the info.
