* Move to a structure instead of pointers to registers
* Autobaud operates per-uart
* When explitily setting uart speed, it applies to all uarts
This allows both UARTs to be enabled and serviced simultaneously,
allowing either accessory port to be used. Note that the last
port to receive something is where subsequent transmits are directed,
and only one set of IAP state is maintained.
To change this, we will need to revamp IAP to support more than
one state machine, and then extend the serial API to allow for both
UARTs to be used independently. Probably not worth the effort.

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,

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)

Making splash -> splashf means its arguments are now checked
at compile time, but the "format" is nearly
always one of our virtual pointers instead of a string/format
literal.
Our gcc494 (and upcoming gcc950) toolchains handle this fine,
but simulator builds with gcc7 complain about this, so suppress
the warning for those environments.
(GCC 12, GCC 14, and GCC15 all seem to be okay with this too)

* 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.

* Use native "hardware mute" for audiohw_mute()
* Properly handle touchscreen inputs

* 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.

* Plugins disabled
* No keymaps to anything else

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

GPT superblocks are located at sector 1 and max_sector-1. If the system
uses a "virtual" sector that's larger than the drive's logical sector,
we need to map those virtual sector numbers to the drive's logical
sector.
If DEFAULT_VIRT_SECTOR_SIZE is defined, try that multiplier as well
as the standard multiplier of 1.
It's not practical to try every intermediate value so instead, if
DEFAULT_VIRT_SECTOR_SIZE is defined, try that as well as the standard
multiplier of 1.
This still leaves a handful of targets that don't set DEFAULT_VIRT
but do set MAX_VIRT.

Basically the GPT is supposed to live at sector 1, but a backup copy is
stored on the final sector.
This gives us a little bit of extra flexibility on systems that might
require sector 1 for other things, but in any case it's a more robust
arrangement.

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.

We normally create a table of the partition sizes/types present
on a drive. Howeever, if the drive is set up as a "superfloppy",
where there is no partition table and a single filesystem starting
at sector 0, this "pinfo" table is not populated.
So now, populate the pinfo table with a single entry that matches
the filesystem type, start, and size.

-Wunterminates-string-initialization will complain if we try to shove
a "string" into a fixed array that is too small. Sometimes this is
intentional; when you are merely using "string" as a standin for
"non-terminated sequence of bytes". In these cases we need to mark
the "string" as "not actually a string" with an attribute. Applies to
GCC >=8, but this warning isn't pulled in by -Wextra until GCC >= 15.
