Samsung YH920 - it uses this detection too, it always should have
the radio.
Samsung YH925 with the radio.
- untested on:
Samsung YH925 without the radio.

Instead of verifying the CRC before every access of the boot data,
verify the CRC once at startup and set a flag to indicate the boot
data is valid.
Also add a framework to support multiple boot protocol versions.
Firmware declares the maximum supported protocol version using a
version byte in the boot data header. The bootloader chooses the
highest version supported by it and the firmware when deciding
what boot protocol to use.

Basically the namespace code _never_ actually linked properly on hosted
targets, but nobody noticed as there were no users, causing the symbols
to be dropped with no fuss.
The tagcache namespace awareness stuff pulled in the namespace code,
which made things go kaboom due to it relying on native FAT parsing
code.

Add HW volume control via ES9018K2M, and reorganize
eros_qn_codec.c/.h, audiohw-erosqnative.c.
This automatically detects the presence of the new DAC and
uses its hardware volume scaling. If not present, use same
SWVOL we have been using so far.
Add debug menu readout of SWVOL/I2C result.
Break out es9018k2m stuff into its own file so that
maybe it can be useful to other ports.
Note that we may need to get smarter about detecting the DAC
type if/when another model emerges.

In my opinion this API is just not very useful - design is kind
of questionable. There are hidden limits on the struct size and
bugs on 64-bit platforms due to assuming sizeof(long) == 4.
At the end of the day, the only major user was the tagcache and
it's actually less code size to do endian swapping manually.

This is intended for improving the effectiveness of tools like
ASAN when debugging memory errors in the sim. It's not meant to
be a serious allocator for hosted targets.
Enable it by changing the buflib backend in config.h.

chunk_alloc allows arrays (or any data) to be allocated in smaller chunks
you have to save the indices..
variable data will have variable indices you need to
store these as [chunk_alloc] doesn't keep track
if you have a fixed size for each
alloc you can do indice / sizeof(data)
or index * sizeof(data) to convert
Lots of debug stuff still in and it needs optimization
User provides chunk_size and max_chunks
max_chunks * struct chunk will be allocated at start
with (1) chunk_size allocation initially
alloc_chunk() with size = 0 shrinks the last allocation to the size of the data used
add OOM checks on buflib_alloc -- oops
move bytes available to the header -- less memory per chunk & better alignment
keep track of the current in use chunk index -- should speed things up a bit
Now allows:
realloc chunk header
larger allocations than chunk size
reallocs smaller than existing will shrink the current array
rather than alloc a new and copy data
Comments welcome :)

replace applicable calls to strlcpy with calls to strmemccpy
which null terminates on truncation
in theory the strmemccpy calls should be slightly faster since they
don't traverse the rest of the source string on truncation
but I seriously doubt there is too much of that going on in the code base

Merge the x1000 and jz47xx exception handling code since they use
the same exception vectors and handlers. The interrupt handler is
now called from the common exception vector, but remains separate
for each board since they have different IRQ layouts.
The new exception handler can provide a stack traceback from the
interrupted code, rather than the (uninteresting) caller traceback
displayed by panicf. This allows you to see what led up to a null
pointer deref or division by zero, which makes it _much_ easier to
track down errors that occur in common leaf functions like strcmp.

Instead of putting "#ifdef LCD_STRIDEFORMAT" at every usage of the
macro it's simpler to have config.h define LCD_STRIDEFORMAT to the
default of horizontal stride when the target leaves it unspecified.

The implementation of write_bootdata() and get_redirect_dir() was
copied verbatim in two different places, obviously a bad thing for
maintainability. This moves them to a new file multiboot.c as they
are only used for multiboot.

Provide definitions for the macros:
* RB_ROOT_VOL_HIDDEN(v) to exclude certain items from the root.
* RB_ROOT_CONTENTS to return a string with the name of the
directory to mount in the root.
Defaults are in export/rbpaths.h
It's a bit much for those that don't need the full functionality.
Some conditional define can cut it back a lot to cut out things only
needed if alternate root mounts are required. I'm just not bothering
yet. The basic concept would be applied to all targets to keep file
code from forking too much.

This caused LCD problems on the ErosQ, where the screen would
go white until being put through a sleep/wake cycle. The exact
reason for this isn't obvious, but the problem didn't exist
prior to the AXP driver rewrite.
The two dependent changes,
42999913ba - x1000: Increase USB current limit to 500 mA at all times
90dd2f84a9 - x1000: Correctly limit USB charging current
ended up bringing the USB charging situation back to where it
was prior to the rewrite, so the cleanest option is to revert
the whole lot.
This reverts commit 42999913ba.
This reverts commit 90dd2f84a9.
This reverts commit 2d89143962.

I noticed a few mistakes in the old driver code and it was in
need of an overhaul anyway... I decided to scale things back,
simplify the code and remove most of the debug menus, netting
a nice code size savings.
One new feature is an advanced debug menu which is accessible
by recompiling the code with AXP_EXTRA_DEBUG. It adds quite a
bit of code size and isn't useful other than for development
so it must be manually enabled by editing the source.

What works:
- LCD: 16-bit RGB565
- all buttons, including scrollwheel
- SD Card
- Battery level and charging/not charging status
- USB
- audio
- sample rate switching
- HP / LO detect, with "safe" fixed LO volume -
LO volume will only be put to user-defined max volume
if headphones are not present.
- rtc
- Plugins build, tried a couple and they seem OK
- Bootloader, installable to nand via usbboot
What doesn't work:
- Dual Boot
- power on/off has intermittent, low volume audio click
(sometimes it's completely silent, sometimes there's
a click)
- Audio uses 16-bit volume scaling, so clicking/popping
is pretty bad at lower volumes - need 32 bit volume
scaling, 24 bit I2S data
- USB HID keys not yet defined
- no jztool support
Unknowns:
- Stereo Switch pins: Direction select, AC_DC
(probably not even hooked up)
- What is the actual purpose of the Stereo Swtich?
- How does the bluetooth module connect?
"Someday" stuff:
- get LCD working at higher bit depth
- Bluetooth

- Audio playback works
- Touchscreen and buttons work
- Bootloader works and is capable of dual boot
- Plugins are working
- Cabbiev2 theme has been ported
- Stable for general usage
Thanks to Marc Aarts for porting Cabbiev2 and plugin bitmaps.
There's a few minor known issues:
- Bootloader must be installed manually using 'usbboot' as there is
no support in jztool yet.
- Keymaps may be lacking, need further testing and feedback.
- Some plugins may not be fully adapted to the screen size and could
benefit from further tweaking.
- LCD shows abnormal effects under some circumstances: for example,
after viewing a mostly black screen an afterimage appears briefly
when going back to a brightly-lit screen. Sudden power-off without
proper shutdown of the backlight causes a "dissolving" effect.
- CW2015 battery reporting driver is buggy, and disabled for now.
Battery reporting is currently voltage-based using the AXP192.

This uses an equivalent algorithm but with a different initial value
than we normally use (all bits off vs all bits on). Use the new crc_32r
to replace the original MI4 crc32 implementation.
This frees up some extra space on mi4 targets which gives us more
room on a few very space constrained targets (sansa c200/e200, etc).

The GPIO API was pretty clunky and pin settings were decentralized,
making it hard to see what was happening and making GPIO stuff look
like a mess, frankly.
Instead of passing clunky (port, pin) pairs everywhere, GPIOs are now
identified with a single int. The extra overhead should be minimal as
GPIO configuration is generally not on a performance-critical path.
Pin assignments are now mostly consolidated in gpio-target.h and put
in various tables so gpio_init() can assign most pins at boot time.
Most drivers no longer need to touch GPIOs and basic pin I/O stuff
can happen without config since pins are put into the right state.
IRQ pins still need to be configured manually before use.

The old name was a bit misleading. AXP173 is sort of the lowest common
denominator of a series of related chips. The M3K uses an AXP192 which

New voltage regulator stuff was added for the sake of the Shanling Q1
native port (that player also uses an AXP192).
