Edits added a couple cross-refenences back into the YP
dev-manual where detailed examples of patching and configuring
the kernel exist.

-Making wholesale or incremental changes to the Linux kernel config can be made
-by including a defconfig or configuration fragments in the SRC_URI.
-
-If you have a complete Linux kernel .config file you want to use, copy it as
-"defconfig" to the ${FILES} directory and add the following line to your
-linux-yocto bbappend file in your layer:
-
-        SRC_URI += "file://defconfig"
-
-Generally speaking, the preferred approach is to determine the incremental
-change you want to make and add that as a fragment. For example, if you wanted
-to add support for a basic serial console, create a file named "8250.cfg" in the
-${FILES} directory with the following content (without indentation):
-
-        CONFIG_SERIAL_8250=y
-        CONFIG_SERIAL_8250_CONSOLE=y
-        CONFIG_SERIAL_8250_PCI=y
-        CONFIG_SERIAL_8250_NR_UARTS=4
-        CONFIG_SERIAL_8250_RUNTIME_UARTS=4
-        CONFIG_SERIAL_CORE=y
-        CONFIG_SERIAL_CORE_CONSOLE=y
-
-Then include this configuration fragment in the SRC_URI:
-
-        SRC_URI += "file://8250.cfg"
-
-At the next build, bitbake will detect the change in the recipe and fetch and
-apply the new configuration before rebuilding the Linux kernel.
