A bit of context, this device is a clone of the FunKey-S with a different form factor, hardware is mostly identical, the relevant difference is it has audio out (via usb-c, adapter to 3.5mm is included), this is the reason why the FunKey-SDK is needed for bulding.
This port is based on the old SDL 1.2 code because the device doesn't have SDL2 support. Alongside what was supported in the SDL 1.2 builds this port supports battery level, charging status and backlight control.

Instead of using the generic hosted sysfs code, which expects
a full path, the ibasso code's sysfs code uses an enumeration.
Unfortunatley the generic power input/charging code used the former
API but linked with the latter. oops.
Correct this by placing a private copy of these functions in
the ibasso-specific port, and removing the generic version from
that build.
(A "proper" fix would be to rework all 17 of the ibasso sysfs calls
to use the generic sysfs API)

documentation for it can be found here:

This is an incomplete port. The bootloader can be loaded using
OpenOCD and it can draw to the LCD using SPI. SDRAM is working
but hasn't been extensively tested.

To keep the code size small, this hardcodes the D-Cache line
size and set/way information (which is defined by the target
and should be fixed for a given CPU) and assumes there is only
one level of cache.

M-profile cores manage interrupts differently from classic cores
and lack the FIQ. Split the interrupt management parts out into
separate headers but keep the endian swapping routines (which are
not profile-dependent) in the common system-arm header.
The initial part of the vector table is common to all Cortex-M
CPUs and is intended to be included by the target linker script,
with the vendor-specific part of the vector table appended to it.

Check for the ES9018K2M dac in the bootloader for
hw1/hw2 devices. Assume that all devices newer than
hw2 have ES9018K2M DAC unconditionally.
All devices will now report the correct hw revision
in the debug menu under Device Data.
Add devicedata.version field, current version 0.
Rename device_data.lcd_version to device_data.hw_rev.
hw2 devices with older bootloaders which ID as hw1 are special-
cased to keep using hwvol on them. They should still upgrade though.

Support hw4 units with AXP2101 PMU
Bootloader successfully compiles and loads onto device.
The LCD appears to be identical to hw3 units.
Scroll wheel and buttons work
Audio output works, including volume.
HP/LO detect works
Rockbox build is generic
GPIO gating logic seems to be working as intended now.
- Added new GPIO definitions - some significant overlaps with pins
from previous hardware revisions...
- Added some GPIO definitions for older players we didn't know about
- Add register definitions for AXP2101 from datasheet
(these are very different from AXP192!)
- Add AXP2101 regulator definitions, need to support multiple step
sizes per regulator.
- Verify AXP2101 voltage set multi-range logic
- Verify AXP2101 voltage get multi-range logic
- Make AXP2101 its own driver
- AXP2101 driver should be "minimally viable", though I think
there is some extra functionality that could be implemented.
- Disabling the coulomb counter stuff - we could maybe make
the E-Gauge work for the same purpose, but it only appears to
be used on the debug screen at the moment so it doesn't seem
like it's worth the effort.
- Found new button GPIOs
- Found error in my GPIO setting logic, blue light works now!
- Set LDO/DCDC output voltages to OF's settings, as far as
I can tell.
- Determined we probably want TCS1421_CFG1:0 to be 0x00,
for UFP behavior
- Tested this rb build with both old and new bootloaders on hw1.5,
hw2, hw4 in as many configurations as I can think of, works across
the board.
- Bootloader can install itself on hw4, so nand chip isn't novel
- Uninstallation file can be made by patcher script, works on hw4
- Installation file can be made by patcher script, works on hw4
- Added HW4 to rbutil, manual

This is a driver for the UART controller on the S5L87xx series of SoCs, which is named after the SoC family.
Since S5L8720 is confirmed to have the same interface and the newer models probably also have it, the driver is renamed to reflect this.

This is a preparation to introduce support for the following SoC models: S5L8720 (iPod Nano 4G, iPod Touch 2G), S5L8730 (iPod Nano 5G), S5L8723 (iPod Nano 6G) and S5L8740 (iPod Nano 7G)
The whole family consists of SoCs which are similar, running ARMv6 and Thumb2 instructions, but some peripherals are located at a different address.
No functional change is to be expected so far.

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.

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

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.
