I hope it will work in futur!

Some modifications:

In arch/ppc/vmliux.lds L2: I replace
'....powerpc-any-elf/lib.'in the variable SEARCH_DIR
by powerpc-linux/lib/ldsrcipt which corresponds to the
path of the environment built with egcs.

I think that the QSPANPCI option isn't necessary
because in arch/ppc/mbxboot/Makefile, CONFIG_MBX
includes qspanpci.o.
I assume the option in menuconfig is for another board
like RPX.

I had problems with the #include <sys/type.h> in the
arch/ppc/mbxboot/qspanpci.c and pci.c because the sys
directory doesn't exist at all.
I commented them out.

I had the following errors during compilation:

m8xx_setup.c: In function `m8xx_init_IRQ':
m8xx_setup.c:280: warning: implicit declaration of
function `cpm_interrupt_init'
m8xx_setup.c:285: `i8259_pic' undeclared (first use in
this function)
m8xx_setup.c:285: (Each undeclared identifier is
reported only once
m8xx_setup.c:285: for each function it appears in.)
m8xx_setup.c:287: warning: implicit declaration of
function `i8259_init'
m8xx_setup.c:288: `mbx_i8259_action' undeclared (first
use in this function)
make[1]: *** [m8xx_setup.o] Error 1
make[1]: Leaving directory
`/home/linux-2.2.5/arch/ppc/kernel'
make: *** [_dir_arch/ppc/kernel] Error 2

In arch/ppc/kernel/m8xx_setup.c:

L270:In the function '__initfunc(void
m8xx_init_IRQ...'

I declared:
extern void mbx_i8259_action(int cpl, void *dev_id,
struct pt_regs *regs);
and
extern void cpm_interrupt_init();

I added an #include "i8259.h" for the i8259_pic
variable.

In arch/ppc/kernel/ppc8xx_pic.c:

I added #include "i8259.h" and <asm/io.h> for the
'inl'
'outb' and 'inb' functions.

I think there's a typo L151: I replace the parameter
'defname' by 'devname'.

And L121 I supprime the 'Static' in the definition of 
 
mbx_i8259_action. (she's used in m8xx_setup.c).

No change with the EXPORT_SYMBOL of ppc_ksyms.c
directory.

In drivers/char/Makefile:L47
I commented out the heading 'arch=m68k...'

And indrivers/macintosh/Makefile:L18
I replace (like Graham) ifndef CONFIG_MBX by 
ifdef CONFIG_PMAC.

Now I try to make a zImage.initrd, but I don't now
very well how to build the ramdisk.image.gz file.

I saw some line like '#RAMDISK = -DRAMDISK=512' in the
Makefile files...?
I don't know to how and especially where the
bootloader is configured (I assume in Head.S mainly).

I hope that somoene had some info on this points and
he could tell them me.

Have a good Day.
Sébastien Tadéoni.
