This caused the devices to crash a few seconds after sending the command. A small power consumption increase is possible when the screen is off with this patch, but Rockbox doesn't crash anymore. Type 0 and 1 are not affected as they use a completely different sequence.
Tested on iPod 6G LCD type 1 and LCD type 2. Type 0 is similar to Type 1, Type 3 is similar to Type 2, so it should cover all available LCD types.

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.

This should allow either accesspory port to be used for IAP comms.
No regressions on an ipodphoto and mini2g through the dock connector,
but I don't have any headset-attached accessories to test against.

This lets us have multiple serial ports enabled, which will help with
4th-gen ipods that have a serial port in the HP jack as well in the dock.

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)

* Use 16-bit audio output
* More audio tweaks (mute on startup, working volume control)
* Treat the rotary input as a scroll wheel (works now)
To-dos:
* Better global keymap (incorporate touchscreen)
* Turn on plugins and define the approximately eight bajillion keymaps
* Still have some audible pops when we turn on, need to figure out why
* Default Cabbiev2 comes off as rather crappy on this device
...I don't know how much work I will do on this thing, as the limited
number of physical controls (and a lack of a line-out) mean I'd never
want to use this thing myself.

* Add a crude keymap
* Use native "hardware mute" for audiohw_mute()
* Properly handle touchscreen inputs
* Can now play back music, with some warts..
Broken:
* rotary wheel still doesn't work
* audio garbled/distorted a bit
* no volume control

Some screens (eg Surfans F28) only report absolute positioning
via "EV_ABS" events, and the actual "touch on, touch off" happens
via a separate "EV_KEY" event. So handle this.
This also fixes a nasty bug introduced in 3270daf2c4.

* Only bootloader builds
* Plugins disabled
* No keymaps to anything else
* No simulator
* Touchscreen not wired up yet
* Audio still untested
Bugs:
* rotary encoder does nothing in bootloader

Other stuff pulled in:
* Unify all of the (identical!) hibyos makefiles
* Rename the "bootloader" to more generic name

We expect a fixed FRAMEBUFFER_SIZE that's width*height*bitdepth, and we
mmap()ed that in. However, when doing the initial fb clear, we
were using the hardware-provided 'finfo.smem_len' which could be
larger than FRAMEBUFFER_SIZE. This overran our mmap and triggered
a segfault.
Correct this by mmaping (and clearing) the entire smem_len. As a safety
measure, panic if smem_len is smaller than our expected FRAMEBUFFER_SIZE

A function that returned bool was an alias for a function that returned
an int. While that original function was limited to returning either 0
or 1, this aliasing is technially a no-no. So create a small shim to
make the warning go away.

This is an incomplete port. The bootloader can be loaded using
OpenOCD and it can draw to the LCD using SPI. SDRAM is working

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.

Cortex-M processors don't have an MMU, but can still have caches
that need software management, so on those platforms we don't want
to include the MMU related functions.
While here, remove an outdated section of a comment referring to
deprecated cache maintenance functions which no longer exist.

Even though ARMv7-M has a hardware divider, 64-bit division is
handled in software and needs a div0 handler. The libgcc routines
call __aeabi_{i,l}div0 so we alias those to __div0.

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.

Commit 1fb906500a ("x1000: LCD DMA fix") caused a regression
on the Q1 by breaking the LCD_X1000_DMA_WAIT_FOR_FRAME logic,
since the wrong branch of lcd_wait_frame() was taken.

All the X1000 targets use "fast" sleep, as opposed to the normal
HAVE_LCD_SLEEP define which creates a user-configurable option.
Remove the ifdefs to make the code a bit easier to read.

perhaps the device takes care of it for you?
hopefully someone with the device notices the issue
(perhaps due to a older battery needing capacity tweaked)

On PATA, we'd cap our transers at UDMA2 if the device reported that an
80 pin cable wasn't detected, but SATA devices do not perform this test.
So alter the check to only apply on PATA devices, so that SATA devices
can run at full UDMA speeds.

On these older iPods, power was not being shut down completely, which led to a backfeed situation leading to decreased battery life and some stability issues.
This was particuarly apparent when using SD card adapters that do not
respect the ATA power management commands (ie all of them), as they never enter a low-power state on their own.
With this change, there are reports of battery life exceeding 20 hours of continuous playback (~30% increase with CF cards, 3x improvement with SD cards) and appears to resolve intermittent wakeup stability issues with SD adapters.
