each type of test.

Improved FVP support.

Better handling of the IPSS FVP when using gcc.
(IPSS FVP is different from other FVP so it still does not work on
normal FVP).

Some correction to Levinson Durbin Q31.

f32, f16 and q31.

This attempts to ensures that even on a 64bit system, the array access
will be treated as a negative number, not a large unsigned offset ending
up reading from the middle of nowhere.

Call osKernelInitialize() similar to ARMCLANG and GNUARM.

* Changing to relu6 to cover both out activation min/max other that the
  default.
* Removing input/output offsets from pooling test data.

* Add new max pool unit test with relu.
* Add some old unit tests that were missing in the generate script so
  that it can be regenerated if needed.
* Add check in generate script for unit tests that are not in the list.

Targetted optimization for GCC when  __SXTAB
is used with __ROR.

Copying linker files and uart code from Arm
Ethos-U Core Platform project.
Updating CMake and README.

Some correction for RFFT Fast f32 in Python wrapper

Array must have a fixed length. Makes use of the existing value range
modifier to indicate the type of each array element.

The format specifier gives hints to the tool about how to graphically
display the configuration option.

Default values can be used in a tool-specific way to implement e.g.
"reset to default" buttons.

Negative numbers are supported by using ".." as the separator between
min, max and step instead of "-", making "-" available to signify the sign.

The legacy syntax is preserved for backwards compatibility.
