As discussed previously on mailing list, we are proceeding with layer
restructuring. For rocko release we will have the following layers
meta-xilinx
->meta-xilinx-bsp (current meta-xilinx)
->meta-xilinx-contrib
In the subsequent releases we will add other layers from Xilinx
meta-xilinx
->meta-xilinx-bsp (current meta-xilinx)
->meta-petalinux
->meta-xilinx-tools
->meta-xilinx-contrib
This will provide one clone to get all the required meta layers from
Xilinx for a complete solution, and the users can blacklist any layer
which they don't want to use using bblayer.conf.
This will enables us to help our vendors/partners to add their reference
designs, board definitions etc.
Recipe changes :
* Move reference design zybo-linux-bd.bb to meta-xilinx-contrib
* Move kernel patches realted to zybo-linux-bd-zynq7 board to
meta-xilinx-contrib
* Update README

With MicroBlaze v10.0 an additional AREA_OPTIMIZED value of 2 was added
named Frequency. This optimization adds additional pipeline stages, and
code can be optimized differently to achieve better tuned performance
for these targets.
The '-mxl-frequency' flag has been added to GCC (not in mainline) to
enable specific tune optimizations for CPUs configured this way.
Whilst this tune does not change any ABI the addition of the 'fo'
package arch flag is added to allow for building both target optimized
and un-optimized without mixing packages.

As of v10.0 MicroBlaze is no longer configurable as a bigendian CPU.
This change prevents the ability to configure the tunes of a MicroBlaze
machine with v10.0 and bigendian.

This change removes the use of the python function to expand the
TUNECONFLICTS definitions for version tunes. Instead this is replaced
with hardcoded definitions. This is preferred due to reduced complexity
of the python code as well as streamlining the include, this is also
done to make the includes align better with expectations of tune
includes in OE-Core.
This change also moves the version conflicts for the reorder tune into
arch-microblaze.
Additional documentation is added to cover details of MicroBlaze CPU
versions, and the change between different version formats.

These versions of the MicroBlaze CPU are now considerably outdated and
were obsoleted in 2012. Additionally they were only available with the
big endian configuration. Remove the v7.30 tune feature.
The s3adsp1800-qemu-microblazeeb machine emulates a v7.10.d cpu version,
however QEMU does not limit the CPU being emulated and provides all CPU
instructions and features that are available, so build targeting v8.00
instead.
Also fix up the version formatting generated by
microblaze_current_version.

The endianess of a specific architecture could be either big or little,
there is not a third value, so let it default to be little endian, and
get rid of the tune feature 'little-endian' which is redundant to be
there, also change tune feature 'big-endian' to 'bigendian'.
With these changes, it will behave same with all other architectures in
openembedded-core layer.

With Xilinx MicroBlaze v8.30 a configuration issue requires that the
'pattern-compare' feature is enable for the 'reorder' feature to be
correctly functional. Previously the MicroBlaze tune setup would assume
that 'pattern-compare' was available even when it may not actually be,
and would force enable the 'pattern-compare' feature automatically. This
behaviour is prone to issues and may emit broken binaries for a target
when the user was not aware or expected that there target CPU was
broken.
This change inverts the behaviour such that instead of implicitly
enabling the 'pattern-compare' feature it instead does not enable
generation of reorder instructions for the compiler by setting
'-mno-xl-reorder' in the same way as the case that the target does not
have the feature enabled.

This change adds the 'arch-microblaze.inc' architecture tune features
include which provides all the relevant tune features for MicroBlaze.
This include replaces the 'tune-microblaze-features.inc' include, which
is not actually a valid TUNE. This change results in the MicroBlaze tune
and tune feature include tree matching the layout of meta/.
This change additionally consolidates all the smaller includes
(feature-microblaze-*.inc) into larger sets or into the
arch-microblaze.inc. This makes the package arch string ordering much
clearer as well as removing the large number of variables uses to set
the TUNE_CCARGS.

Clean up the MicroBlaze versions tunes as well and improve the
TUNECONFLICTS for version features so that the conflicts matrix is
automatically generated. Additionally consolidate the version features
into a single include.
Improve and generate the "-mcpu=" and package strings based on the
version feature.
