64bb720edf Coldfire: Optimize emac context save/restore in mixer ISR.
Save only once if emac is used in ISR and restore only once per ISR
call if already saved.

286a4c5caa Revise the PCM callback system after adding multichannel audio.
Additional status callback is added to pcm_play/rec_data instead of
using a special function to set it. Status includes DMA error
reporting to the status callback. Playback and recording callback
become more alike except playback uses "const void **addr" (because
the data should not be altered) and recording  uses "void **addr".
"const" is put in place throughout where appropriate.

Most changes are fairly trivial. One that should be checked in
particular because it isn't so much is telechips, if anyone cares to
bother. PP5002 is not so trivial either but that tested as working.

9a25a6fe19 beep/mixer code: Code police a bit.
/firmware is in the #include path with makes #include "asm/beep.c" sufficient.

Add a comment to generic beep code and make another express intent better.

9a32a7b404 Split CPU-optimized beep code into the firmware/asm tree.
For now due to current lack of an apps/asm, place the ASM/generic code in the
firmware/asm directory.

Additionally, make generic beep code more generic.

43e6d7aef8 Urgh...actually change all the stuff I'm supposed to.
Goofed a couple fn params.

Also remove unused firmmware/asm/generic directory.

67dd4d6995 Generic find_first_set_bit can use __builtin_ctz instead of __builtin_ffs
The former gives 0-based indexes, which is what our implementation returns,
making the "- 1" unnecessary.

8e8e978de6 Add framework to let make automatically pick optimized asm implementations over generic C ones to firmware.
Example: for a file asm/foo.c, make will look for asm/arm/foo.[cS] and
compile it if found. If not found it'll fall back to asm/foo.c.

Also introduce new ARCH make variable. This is automatically detected by
configure. It is distinct from CPU since CPU defines the dir used for
the target tree (i.e. firmware/target/X, so it can be "hosted").
ARCH really has the target isa and can be x86 for sims/raaa too.

991ae1e395 Create fimrware/asm directory for assembly optimized stuff.
This dir is suitable for stuff that doesn't fit the target tree, e.g. because
it also builds on hosted or otherwise. It also has a generic subfolder for
fallback C implementations so that not all archs need to provide asm files.

SOURCES should only contain "foo.c" where foo.c includes the specific
<arch>/foo.c files from the subdirs using the preprocessor. This way automatic
selection of asm versions or generic C verion is possible.

For the start, the thread support files are moved, since ASM threads can
be used on hosted platforms as well. Since core_sleep() remains platform
specific it's moved to the corresponding system.h headers.
