[linux-yocto] [PATCH v3 00/12] ktype refactoring: move DEBUG_KERNEL, EXPERT and EMBEDDED

[California Sullivan]

Targetted for yocto-4.4 and master

Changes since last revision:

*Removed branch command from developer ktype*
Including standard does this already.

*Removed "default policy" comment from -developer common-pc BSPs*
This was copied from the -standard BSPs and is no longer accurate.
I could have changed standard to developer in the comment, but I don't
feel comfortable asserting that this is the default policy for developer
kernels when more is likely to be added.

*Updated commit messages*
Explain that standard is now for production in "add developer common-pc BSPs" patch.
Fix typo in subject line of "inlcude developer ktype instead of standard" patch.

*Patches aren't 00/12*
That was embarassing.

This patch series refactors the ktypes so that base and standard ktypes
do not enable EMBEDDED, EXPERT, or DEBUG_KERNEL. The reason this
decision was made is because production platforms likely do not want
DEBUG_KERNEL enabled, and EMBEDDED selects EXPERT which selects
DEBUG_KERNEL.

A new ktype called "developer" was also created. This ktype
enables the options now missing from standard and base, making it easy
to maintain the functionality of a BSP through simply swapping the ktype
from standard to developer. The preempt-rt ktype is now based off of
developer in order to maintain its functionality.

The new standard ktype does not include EMBEDDED, EXPERT, or
DEBUG_KERNEL. Without DEBUG_KERNEL it loses a number of debug features
that are selected by default. Without EXPERT it gains RFKILL_INPUT and
DEBUG_MEMORY_INIT, while losing VMSPLIT_3G. These are only available to
configure with CONFIG_EXPERT=y and default to EXPERT or !EXPERT. Not
selecting EMBEDDED has no apparent impacts.

Some coordination is required for this change, as existing BSPs WILL be
affected, and will either need to accept the changes in the standard
ktype or move to the developer ktype.
