[Buildroot] What is procedure for building custom Linux-2.6.36 from BuildRoot?

[Charles Martel]

I noticed that BuildRoot will build a linux-2.6.36 kernel using default values. What is the procedure for building a custom build of the Linux kernel?
Specifically, BuildRoot builds SPI Drivers as modules (.ko) by default. I'd like to have the SPI Drivers built-in (Y instead of M) and also have the UserSpace SPIDEV built.
Can this be done from BuildRoot or must I rebuild the Linux kernel after building the BuildRoot filesystem?

Also, I had to modify the Makefile to not wipe out the Linux .config file when I execute "make clean". Is there a better way to store the customized values in Linux .config as part of the BuildRoot build configuration?

Thanks.

Hello Charles,

From the buildroot configuration tool, in the kernel submenu, you can
select a "custom tarball" kernel (which might be a 2.6.36 in your
case) and also a "custom config file".

But if you're going to hack on your kernel, it make sense to make a
separate build.

Regards,

And to adjust the kernel configuration, you can do:

 make linux26-menuconfig

or

 make linux26-xconfig
