6db80020b4 Do some housekeeping with fat.h and SECTOR_SIZE
Many includes of fat.h are pointless. Some includes are just for
SECTOR_SIZE. Add a file 'firmware/include/fs_defines.h' for that
and to define tuneable values that were scattered amongst various
headers.

Remove some local definitions of SECTOR_SIZE since they have to be
in agreement with the rest of the fs code anyway.

(We'll see what's in fact pointless in a moment ;)

70c929179b Dircache: Refine name allocation and error handling.
* 8 bits is enough to allow 260 character base names when five
bytes is the minimum indirect storage size (0..255->5..260).

* Don't truncate anything that's too long as that can lead to
bad behavior, simply don't include the offending entry in the
parent.

* Set the .tinyname flag to 1 by default to indicate that
the entry's name doesn't need freeing. Clear it only when
allocating indirect storage.

* Rename some things to help catch all instances

e3081b35cd Fix a couple dircache oopsies.
Moving binding from queued to resolved was messed up if it was the
first queued one and there were other resolved files open at the
time of resolving it.

Dircache info for a directory about to be recursively scanned should
be filled before opening it. Would only affect a directory if it
happened to be opening while it was being initialized.

8ff1b6b603 Remove FF_CREAT and FF_EXCL flags in from file code.
These flags aren't stored for an open file because they're simply
actions for open() to take, corresponding to O_CREAT and O_EXCL.
Just pass the oflag argument along to the deeper call, with some
minor filtering.

dc22522c2c Tweak a few tagcache things.
* Take out pointless dircache_search; nothing can be reconstructed
with the given info in find_entry_ram(); don't even try there.
Path AND index id must be known. Work it out later.

* Timed yield must be far more often than once every 1/4 second (?!)

* Do better the memory-remaining checks for ramcache load.

* Root separator mustn't be doubled up when searching files.

fc9695eb47 Improve radio RDS driver and framework
* Remove unused bits like the radio event and simplify basic
radio interface. It can be more self-contained with rds.h only
required by radio and tuner code.

* Add post-processing to text a-la Silicon Labs AN243. The chip's
error correction can only do so much; additional checks are highly
recommended. Simply testing for two identical messages in a row
is extremely effective and I've never seen corrupted text since
doing that, even with mediocre reception.

Groups segments must arrive in order, not randomly; logic change
only accepts them in order, starting at 0.

Time readout was made a bit better but really we'd need to use
verbose mode and ensure that no errors were seen during receiving
of time and more checks would be need to have a stable PI. The
text is the important bit anyway.

* Time out of stale text.

* Text is no longer updated until a complete group has been
received, as is specified in the standard. Perhaps go back to
scrolling text lines in the radio screen?

* Add proper character conversion to UTF-8. Only the default G0
table for the moment. The other two could be added in.

* Add variants "RDS_CFG_PROCESS" and "RDS_CFG_PUSH" to allow
the option for processed RDS data to be pushed to the driver and
still do proper post-processing (only text conversion for now for
the latter).

6436c6e749 Fix tagtree from blowing up when its buffer moves
I noticed that after booting with the external storage removed,
playing from tagtree, inserting the card, forcing dircache to
reallocate from the debug screen, and trying to reenter tagtree,
it would data abort because the dircache reallaction to a larger
size caused the tagtree buffer to move.

Adjustment to at least one pointer (csi) was missed. Since it's
non-trivial there to determine when things should be NULL and
when they shouldn't, add check for menu too before moving it.
As for the rest, who knows.

72dc239299 Make sure dircache resolves outstanding references on volume root.
If a volume root was open at the beginning of a build, its dircache
reference wouldn't be resolved on an already open volume root
directory because the call to do it was simply omitted. Nothing
horribly bad unless a root were opened at mount time and kept open
long term.

29c493dd74 Fix a bug in disk.c that really wasn't affecting anything.
volume_onmount_internal() was being given the next volume to mount
instead of the one just mounted. Only dircache was being notified
for now, which always attempts to scan everything that needs to be
rebuilt, currently making the volume parameter value immaterial.

Put things in the right place and also set the disk sector
multiplier before notifying anybody of the new volume.

d7871914ac Fix dangerous casts
On Windows 64-bit, the size of long is 32-bit, thus any pointer to long cast is
not valid. In any case, one should use intptr_t and ptrdiff_t when casting
to integers. This commit attempts to fix all instances reported by GCC.
When relevant, I replaced code by the macros PTR_ADD, ALIGN_UP from system.h

1245c5fe61 Implement speaker enable/disable on jack (un)plug
The implementation is not very complicated but there are a few things worth
noting. There was a previous "speaker enable" setting but it was a boolean.
I decided to replace it with a choice setting that has 2 options (on, off)
if headphones cannot be detect on this target, or 3 options (on, off, auto)
if we can detect headphones. This will break the old setting on target that
cannot detect jack but it makes the code more uniform and avoid maintaining
two settings with more #ifdef. The third option (auto) uses the LANG_AUTO
text, which I think is clear enough (disable speaker on jack plug).
In order to avoid code duplication (both in apps and firmware), I decided to
keep the audiohw_enable_speaker function as-is: it takes a boolean and doesn't
care about the speaker policy. I introduced a new audio_enable_speaker that
takes directly the mode (which follows the setting encoding): 0=off, 1=on
and 2=auto. This way one calls audio_enable_speaker and it changes the speaker
once to reflect the request mode. The apps code then uses this function in the
places where it makes sense: on setting load, setting change and jack (un)plug
event.

c156c5f5e5 zen/zenxfi: adjust maximum emi voltage
Running at 130MHz is unsafe since on those targets, we disable memory frequency
scaling because it is unstable. That leads to situation where cpu is running at
64MHz and VDD is at 1.050V. But on STMP3700, the EMI uses the VDD rail instead
of a dedicated VDDMEM rail as on STMP3780. Thus we are essentially running the
EMI at 130MHz at 1.050V when the minimum recommened voltage is 1.2V. This commit
runs the EMI at 64MHz all the time on the ZEN and ZEN X-Fi which will lead to
reduce performance but hopefully increases stability.

epoch start.

As a bonus, handles negative time values.

It is possible to have a thread awoken and subsequently the message
that was placed in the queue has been removed by the time the thread
is able to check the queue. Ensure theads that failed to find a

It was at worst imprecise when a timeout is specified. It's entirely
incorrect if the function ever returns with SYS_TIMEOUT when using
TIMEOUT_BLOCK.

783c77531c AMS: Return ascodec to interrupt-based I2C2 driver
1. Slightly revised and regularized internal interface. Callback is used
for read and write to provide completion signal instead of having two
mechanisms.

2. Lower overhead for asynchronous or alterate completion callbacks. We
now only init what is required by the transfer. A couple unneeded
structure members were also nixed.

3. Fixes a bug that would neglect a semaphore wait if pumping the I2C
interrupts in a loop when not in thread state or interrupts are masked.

4. Corrects broken initialization order by defining KDEV_INIT, which
makes kernel_init() call kernel_device_init() to initialize additional
devices _after_ the kernel, threading and synchronization objects are
safe to use.

5. Locking set_cpu_frequency has to be done at the highest level in
system.c to ensure the boost counter and the frequency are both set in
agreement. Reconcile the locking inteface between PP and AMS (the only
two currently using locking there) to keep it clean.

Now works fine with voltages in GIT HEAD on my Fuze v2, type 0.
Previously, everything crashed and died instantly. action.c calling
set_cpu_frequency from a tick was part of it. The rest may have been
related to 3. and 4. Honestly, I'm not certain!

Testing by Mihail Zenkov indicates it solves our problems. This will
get the developer builds running again after the kernel assert code
push.

9bb6050d40 hwstub: rewrite exception catching
Since we can catch exceptions like data aborts on read/write, it takes very
little to also catch exceptions in calls. When extending this with the catching
of illegal instructions, the call instruction now becomes much more robust and
also for address and instruction probing. Since we can catch several types of
exception, rename set_data_abort_jmp to set_exception_jmp. At the same time,
simplify the logic in read/write request handlers. Also fix a bug in ARM
jump code: it was using
  stmia r1, {..., pc}
as if pc would get current pc + 8 but this is actually implementation defined
on older ARMs (typically pc + 12) and deprecated on newer ARMs, so rewrite the

f3cce72269 hwstub/jz460b: implement exception recovery
Now that we now that jz4760b implements EBASE, we can use it to rebase
exceptions to use a k1seg address, that maps to the physical address of the
TCSM0. It requires to enable HAB1 to have this translation. This most the most
inefficient way to access tighly coupled memory ever, but it works.
