Convert i.MX31 and AMS target to use RTC interrupt

2017-11-21T12:52:02+00:00

Instead of checking ticks, set a sticky dirty flag that indicates
that the RTC needs to be read. This gives a timely update and more
accurate readout without actually reading the RTC until it changes.
The implementation should atomically read the flag and clear it.
Setting the flag would typically happen in an RTC tick ISR.

Implement a much more capable vuprintf()

2017-11-21T10:00:27+00:00

New support as well as some buggy support fixed.

Still no floating point support if ever that would be desired.

Support (*):
* Flags: '-', '+', ' ', '#', '0'

* Width and precision: 'n', '.n', '*' and '.*'

* Length modifiers: 'hh', 'h', 'j', 'l', 'll', 't', 'z'

* Radix: 'c', 'd', 'i', 'n', 'o', 'p/P', 's', 'u', 'x/X'

(*) Provision exists to switch lesser-used stuff on or off or when
certain functionality isn't desired (bootloader?). The compulsory
radixes are everything but 'o', 'n', 'p/P' and 'x/X' with length
modifiers being optional. The default setup is 'l', 'z', 'c', 'd',
'p/P', 's', 'u', 'x/X'.

* Move fdprintf() to its own file. It was in a strange place.

* Make callers compatible and fix a couple snprintf() bugs while
at it.

Could smush it down in size but I'm gonna get over the binsize
neurosis and just the let optimizer do its thing.

Imx233 Disable Autoslow only at maximum cpu frequency

2017-11-12T13:28:03+00:00

At normal loads:
- disabling auto slow boosts performance at the cost of runtime (~ -5%)
- disabling at max cpu does not noticibly decrease runtime

AMS: Convert ascodec_endofch() to use bit mod function's return value.

2017-10-31T02:12:58+00:00

It cleans up the code and it was the initial inspiring reason to
change them.

Make atomic bit modification functions return previous value.

Add boot data support to rockbox.

2017-10-29T16:50:59+00:00

Bootdata is a special location in the Firmware marked by a magic header
The bootloader is able to copy information to the firmware by locating
this struct and passing data to the firmware when it is loaded but
before it is actually executed

Data is verified by a crc of the bootdata
