We don't have any devices that usefully use ION but this at least
ensures that we have build coverage.

It has not been backported, we will have to take a decision about
backporting any extra support and what will be included.

Android uses threads with very low priority by default to implement
AsyncTask APIs. This means that applications making use of these
APIs to produce multithreaded code are penalised by not allowing
use of big CPUs as necessary.

Currently there are two ways of passing list of fast-slow CPU's to kernel. One
via configs and other via DT. Code tries to get them via configs first an then
try for DT.
To make it configurable via DT by default, make config strings empty.

CONFIG_HMP_FAST_CPU_MASK and CONFIG_HMP_SLOW_CPU_MASK must be set correctly by
user platform. For now they are marked 0-1 and 2-3.

Performace and power don't appear to be improved by building for ARM,
in fact, there's a suggestion it uses slightly more power.

For now, lets play safe and not disable any tracing and profiling
options in case these are expected to be present for benchmarking
purposes.

Use ARM rather than Thumb2 and disable debug and trace features which
aren't essential. (Some trace features are still needed to avoid
breaking Gator).

Note, for the sake of a faster boot and better performance, we default
to maximum CPU clock frequency (CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE)
and will rely on user-side scripts on Android and Ubuntu to change this
as appropriate for big.LITTLE power saving. E.g. changing LITTLE cores
to 'ondemand'.

To provide access to LEDs enable

(LED's are available from user side under under /sys/class/leds)
To use the motherboard LEDs to show CPU activity...

the config fragment is now used for booting various distributions like
Fedora, OpenEmbedded, Ubuntu. It isn't specific to Ubuntu anymore.
Remove ubuntu.conf: the config fragment is unused.
