Or do I need to patch more into immap_85xx.h on my own? I just want to avoid to do duplicate work. Or is it better to extend the fsl_ocp or the platform device structures? What do you plan on doing with the local bus controller in the kernel? If this is only configuration of the controller for a given chip select that I would suggest doing something similar to how we handle PCI. You can probably find a description of the localbus registers in the u-boot source tree. Is this a change you want to get back into the mainline kernel tree? - kumar
Cross compiler
I'm trying to use crosstools to compile a gcc-3.4.3/glibc-2.3.4 for ppc-604 (actually for mpc826x) on i686. which version of crosstools? Crosstools-0.31 Anybody know of a solution? have you checked out: http://www.wwwdotorg.org/writings/code/nptl_tool/nptl_tool.html Thanks, I'll have a look at that link.

[PATCH] ppc32: Added preliminary support for the MPC8548 CDS board
Adds support for using the MPC8548 processor on the CDS reference board. Currently all the major busses (PCI, PCI-X, PCI-Express, sRIO) and eTSEC3 and eTSEC4 are not supported.

Complete ccsr map for mpc8540 available?
Hello, Kumar! Yes, I want to add another Local Bus Address Range for our FPGA on an extra CS line. I've tried to do that in U-Boot as the Code is already there. But my modified (some old 1.1.2 (not the official release) version) U-Boot didn't work (I guess compiling issues) and rendered my Board non-bootable, which was really no fun! I also want to play around with the bus-timing and GPCM/UPM configurations. So, changing U-Boot for every little waitstate and re-booting just to get a register changed is a showstopper for me. (Yes, I know, a BDI2000 would be fun). So I decided to do all my stuff first in linux in a module to shorten the design cycle by a factor of 1E+3 which works fine now, as I started this immr_t thingy for mpc8540 on my own... Now it seems that u-boot's immap_85xx.h is pretty much what I was looking for, I will try to merge my stuff with it and get a immap_8540.h out of it. So, you answered my question indirectly (get back to mainline) that there is no code available on the linux side yet, right? I can release my stuff, if anybody is interested... no problem. The LBC part is verified (some others are dummys and untested) and in a /works for me/ state.

Dynamic libraries do not work
I 've found the problem, the ramdisk used contained executables as well as dyn. libs from the mpc8260 instead of the mpc862. I don't know why the whole system came to a halt without any message but replacing the dyn. libs and executables with the correct ones solved the problem of crashing.

set_multicast_list() commented out in fcc_enet.c
Hi Alex, I had the same problem few months ago with arch/ppc/cpm2_io/fcc_enet.c. It should be the same driver. I suppose that multicast is not correctly implemented. I have commented this return and promiscuous mode works fine but I have never tried with multicast.

There is no comment saying why it is there. An effect of this is that you cannot put the device in promiscuous mode, which is required when adding it to a bridge. Please can anyone say why this return; is there?
