kernel for MPC8260 SBC

kernel for MPC8260 SBC

[Suresh Chandra Mannava]

Hi,

We developed a SBC based on MPC8260. We are planing to port Linux on it.
I downloaded mpc8260 cross compiling tools from denx.de.

I started cross-compiling linux-2.4.4.
The problem is
I am not able to compile kernel. 8260 specific files in arch/ppc are not 
compiling due to not inclusion of
"bd_t" structure. I Included the file "asm-ppc/bseip.h".
Still encountering many errors.

I even tried with linux-2.4.20 and encountered the same problems.
Is there any patch required for compiling the kernel cleanly.

or
I may need to provide board specific information in the form of header 
files?

Please provide pointer to the sutiable kernel along with patch.

We have configured serial port on SMC. For SMC, CPM is required.
But there is no option in the kernel to select SMC for serial port.

please educate me on the above issue.

Thanks & Regards,

Suresh Chandra Mannava

Why? 2.4.4 ist very, very old. Use a more recent kernel tree. If  you
want   to   stay   in   our   source   tree,   then  please  use  the
linuxppc_2_4_devel module on our CVS server.

Then your configuration is broken. The kkernel compiles fine for many boards.

This is not a big surprise. The "bseip.h" header file is for a MPC8xx
based board - what makes you think that this might work on your  8260
based hardware?

No. There is no patch needed. The kernel trees are  clean.  You  just
have  to  select a correct configuration. Ummm... and for your custom
board you will probably have to port Linux first.

See for example the linuxppc_2_4_devel module on our CVS server.
