Problem building 2.6.34 for neek due to CPU_ prefix

Hi,

I'm new to NIOS but not embedded linux.

I am using a neek and can succesfully boot the precompiled 2.6.34 image.

I have got the latest 2.6.34 sources from GIT.

Compîling for neek with CONFIG_NIOS2_NEEK_OCM works but crashes on boot (which is quite normal since it doesn't correspond to my design)

However if I use CONFIG_NIOS2_CUSTOM_FPGA and put the result of sopc-create-header-files in arch/nios2/boards/neek/include/asm/custom_fpga.h the compilation fails with errors like: 

arch/nios2/kernel/asm-offsets.c:127: error: 'ICACHE_SIZE' undeclared (first use in this function)

When I compare my custom_fpga.h with the original one it appears that a lot of the CPU related definitions are now prefixed with CPU_ (I am using v9.1sp2 of the Altera tools to do the generation)

I can probably hack around this by adding some defines to nios.h but what is the right way - am I missing somethng?

Thanks,

Martin

    Ok (replying to my own post),

    problem solved - I didn't give the --single option to sopc-create-header-files

    with that all works fine, no hacks required.

    Sorry for the noise,
