Compiling Linux Kernel for ML403

[Magnus Hjorth]

Hi Mohammad,

The files that are in generated in the BSP are for an older mvista kernel (based on 2.6.14 I think) and some things have changed since then. In particular some tables in virtex.c and xilinx_ml403.c are different. It's probably easier to fix these files manually than to copy the files from the BSP. 

You should rename the xparameters_ml40x.h in the BSP to xparameters_ml403.h. You may also need to add some #defines for constants that have changed names, which you will discover when you try to compile the kernel. 

You need to manually edit Kconfig files to get menuconfig entries, and you will need to edit some Makefiles to get it all to be compiled in. It could be easier in mvista, I don't know... Good luck!

Best regards,
Magnus

Obviously, It generates some error messages, Is this  kind of behaviour natural? I was not expecting to see syntax errors in kernel source tree ? ( Of course, when I build the kernel without Xilinx BSP every thing is OK )
