I'm using 2.6.25.8, but I think it's the same for all 2.6.25 kernels.
I set: ARCH=powerpc, CROSS_COMPILE=powerpc-linux-gnuspe-
The cpu is Freescale 8548, so "Processor Type" is Freescale 85xx
First, there's no Kconfig entry for rapidio, as it seems stuck in the
ppc subtree, with bad guarding condition (around line 1097 in
arch/ppc/Kconfig), so I just copied it into arch/powerpc/Kconfig (without
the conditional for now).
And now for the build errors:
Stage 1:
arch/powerpc/kernel/rio.c:17:21: error: asm/rio.h: No such file or
directory
Stage 2 (after fixing stage 1):
arch/powerpc/sysdev/fsl_rio.c: In function ârio_open_outb_mboxâ:
arch/powerpc/sysdev/fsl_rio.c:455: error: âMPC85xx_IRQ_RIO_TXâ undeclared
(first use in this function)
arch/powerpc/sysdev/fsl_rio.c:455: error: (Each undeclared identifier is
reported only once
arch/powerpc/sysdev/fsl_rio.c:455: error: for each function it appears in.)
arch/powerpc/sysdev/fsl_rio.c: In function ârio_close_outb_mboxâ:

arch/powerpc/sysdev/fsl_rio.c:916: error: âCCSRBARâ undeclared (first use
in this function)
And the worst thing is - those macros are defined using old style ppc
register defines and I don't have a nearest idea how to fix it on a new
style kernel (for one - CCSRBAR is replaced with some runtime thingie).
