The PPC e5500 is a 64-bit core so we add both a 32 and 64-bit set of
tune files to allow for:
* pure 32-bit build
* pure 64-bit build
* 32-bit base, 64-bit multilib
* 64-bit base, 32-bit multilib

We need --with-cpu based to glibc to get proper support on 603e & e500mc
to pickup proper math libs to deal with sqrt. These core do not
implement the fsqrt[s] instructions that the normal PPC math libs
utilize.
This causes use to not set AVAILTUNES specifically to the sub-arch only
as we arent generically compatiable.

The previous commit to this file meant thumb was always being turned on
even when TUNE_FEATURES did not contain "thumb". This is clearly wrong
and this patch corrects this so thumb options are no longer specified
in that case.

We need to ensure only one value ends up in TUNE_PKGARCH rather than several.
This change ensures consistency accross all the PPC tune files and that they
correctly inherit the core value but also allow it to be overwritten.

PACKAGE_EXTRA_ARCHS_tune-armv5eb needs to be defined in terms of
the non-e with the same endianness, i.e. PACKAGE_EXTRA_ARCHS_tune-armv5b
not PACKAGE_EXTRA_ARCHS_tune-armv5, otherwise PACKAGE_EXTRA_ARCHS will
end up containing a semi-random mixture of endiannesses and disaster
will ensue. Likewise for the vfp and armv6 variants.
This is all a bit confusing because TUNE_FEATURES is done the opposite
way around, i.e. TUNE_FEATURES_tune-armv5eb is derived by taking the
armv5e version and adding bigendian. But fixing that is probably
a subject for a separate patch.

files and tune features
These changes revolve around the idea of tune features. These are represented by
'flag' strings that are included in the TUNE_FEATURES variable.
Any string included in TUNE_FEATURES should also add a TUNEVALID[<name>] entry so
we can know which flags are available in TUNE_FEATURES and have documentation about
what the flags do. We will add sanity code to error if flags are listed in
TUNE_FEATURES but are not documented in TUNEVALID.
A given tune configuration will want to define one or more predetermined sets of
_FEATURE flag lists. These are defined in the form TUNE_FEATURES_tune-<name>.
For defined tune configuation, <name> should be added to the AVAILTUNE list so that
we can determine what tune configurations are available. Flags cannot be used in this
case as with TUNEVALID since its useful to be able to build up tune lists from other
TUNE_FEATURES_tune-yyy options.
A given tune configuration may also define PACKAGE_EXTRA_ARCHS_tune-<name> and
BASE_LIB_tune-<name> to control the multilib location. All options can be overridden
by the distro or local user configuration.

Since we're updating the tune file format, it makes sense to abstract
the compiler tune arguments at this point too. This means that should
these need to be overridden at any point, the original values can
still be obtained in a similar manner to the other TUNE* variables.
Whilst this isn't strictly necessary for any current need, its likely
good practise to standardise this behaviour.

There is currently consideradble confusion over how the tune files operate
and how these interact with the rest of the build system. This update/overhaul
changes things so the tune files are primarily resonsible for setting:
TUNE_ARCH - What was formerly set as TARGET_ARCH and is the value that
represents the architecture we're targetting.
TUNE_PKGARCH - The value that represents the tune confuration that this set
of tune parameters results in.
This allows the significant improvement that the core can now always determine
the target architecture value, even when TARGET_ARCH needs to be reset to
something different and likewise, there is one package architecture variable
the core can reference allowing simplification of the BASE_PACKAGE_ARCH, PACKAGE_ARCH
and FEED_ARCH variables.

This basic cleanup removes the _ext2/3 overrides from places they
no longer belong since they did not allow further overrides. In doing
this the core-image-minimal* recipes can now set a reasonably small
rootfs so that it's a realistic size for minimal.
The new default for minimal is 8M and will be adujsted upward by the
IMAGE_OVERHEAD_FACTOR (default of 1.3).
This also fixes the ROOTFS_SIZE usage in the IMAGE_CMD_<fstype> code

There is a problem with the current PACKAGE_EXTRA_ARCHS implementation
since its impossible to control which extra architectures sort higher
than TARGET_ARCH and which sort lower. In the x86 case for example,
TARGET_ARCH might be "i586", i486 should be lower than this and i686 should
be higher. There are also complications where its easy to inject duplicate
entries into the variable.
I tried various versions of this patch and concluded that it was simplest
just to force the tune files to include TARGET_ARCH in the list in the
right place if they're planning to customise it themselves. Other approaches
with appends and prepends just complicated the code for no good reason.
The TARGET_ARCH definitions should also move to the tune files but I'll
leave this for a separate patch.

In order to extend and create more kernel recipes based on the
supported yocto kernel common routines need to be placed in
re-usable blocks.
To accomplish this meta/recipes-kernel/linux/linux-yocto_git.bb
is broken into three parts:
- meta/classes/kernel-yocto.bbclass: contains common routines
for checking out and configuring a yocto kernel git repository.
This should be inherited by recipes that need this functionality.
- meta/recipes-kernel/linux/linux-yocto.inc: Contains the machine
mappings, compatibility, build directives and common task
definitions for a yocto kernel based recipe. This inherits
kernel-yocto, and is the typical point of entry for other recipes.
- meta/recipes-kernel/linux/linuux-tools.inc: tasks and function definitions
for kernel recipes that want to build/export perf
It also updates the linux-yocto recipe to default to 2.6.37.
As part of the update to 2.6.37 the branch naming and conventions
have been modified to show inheritance, and be more generic.
For example:
master
meta
yocto/base
yocto/standard/arm_versatile_926ejs
yocto/standard/base
yocto/standard/beagleboard
yocto/standard/common_pc/atom-pc
yocto/standard/common_pc/base
yocto/standard/common_pc_64
yocto/standard/fsl-mpc8315e-rdb
yocto/standard/intel_atom_z530
yocto/standard/intel_core_qm57_pch
yocto/standard/mti_malta32_be
yocto/standard/preempt_rt/base
yocto/standard/preempt_rt/common_pc
yocto/standard/preempt_rt/common_pc_64
yocto/standard/preempt_rt/intel_atom_z530
yocto/standard/preempt_rt/intel_core_qm57_pch
yocto/standard/qemu_ppc32
yocto/standard/routerstationpro
In this structure:
master: tracks the mainline kernel
meta: meta information for the BSPs and kernel features
yocto/base: baseline kernel branch
yocto/standard/base: 'standard' kernel, contains features
and configs for all BSPs
yocto/standard/<machine>: represents a BSP with specific
features or configurations
The tools, tree and libc-headers have all been updated to
deal with this new structure. Also in addition to dealing with
the new structure, they continue to work with the existing
tree and will adapt at runtime to the differences.
The linux-yocto-stable_git.bb recipe continues to build the
2.6.34 based tree,and linux-yocto_git.bb builds 2.6.37. As
boards are enabled for the new kernel they will move from
-stable to the development kernel. As of now, only the
emulated targets have moved to 2.6.37-rcX

The existing preferred yocto kernel wasn't named appropriately
and needs to be updated.
In keeping the changes small and isolated, this commit simply
renames the recipe and some internal variables. Future commits
will refactor the code into more usable blocks.
Now that linuy-wrs has been renamed linux-yocto, we need
to rename and update an board configurations and append
files.
Now that linux-wrs has been renamed linux-yocto, we need to
update the SRCREVs to have the new name.
