To: buildroot
Here is the target/linux/Config.in and target/linux/Makefile.in
that I use in my local buildroot from 2007-05-31.
(Did not test it against the latest buildroot, which obviously
needs to happen)
It allows me to:
* Build the linux kernel
* Select the binary type using a menu choice or free text.
* Select which kernel version to use.
(Will obviously have to add the latests kernel version)
* Can generate a .config using make XXXX_defconfig
* Can perform "make xconfig" before Linux kernel is built
* Can select to copy the linux kernel into the root fs
* Can copy to secondary location (defaults to /tftpboot)
Would like some comments...

Nice!
I'm eager to test this.
For future emails, could you please attach the files/patches rather
than put the inline in the message body? Copy-pasting is tedious and
error-prone, and inlining prevents MUAs from displaying an "has
attachment" icon/label.
Thanks,

I am thinking of submitting this as an optional (experimental) way
of configuring the linux kernel, with default to the original
way of doing things. I.E: you have to actively set a flag
to use the experimental configuration.
Then it will be easier to test and provide feedback.
Is this an acceptable way to proceed?
Will update to use the latest kernels including mm and git patches
before I submit.
Best Regards

IIRC, It was created before linux26.mk, so there is very little common
things.
I expect that a diff would mostly delete linux26.mk and create
the Makefile.in.
Will do it anyway.
