[yocto] How to patch a recipe .inc file

[Greg Wilson-Lindberg]

Hi Jonas,
I have added extra kernel config through a .bbappend and a do_configure_append() function. The issue that I was asking about is that the for the initramfs changes that are suggested in the meta-raspberrypi documentation, section 3.14, they need to be inserted in the middle of one of the functions in the linux-raspberrypi.inc file, they can't be added in a prepend() or append() function. This either requires that I change the linux-raspberrypi.inc file or find some way to patch it during the build, I would prefer to patch it.

Regards,
Greg Wilson-Lindberg
