Simply extends the current isqrt() to be able to do fractional bits
and improves the initial estimate using clz(). iqrt() itself is
no more and is equivalent to fp_sqrt(x, 0). The original also had
a small bug where the guess comparision should have been >=, not >.
Uses no large integer math or division and is very accurate
(simply returns a truncated fraction).

seems more logical to me, and is more consistent, since
"SAMSUNG_YH92X_PAD" is already used in the tex files.

The port to for this two targets has been entirely developped by Ilia Sergachev (alias Il or xzcc). His source
can be found at https://bitbucket.org/isergachev/rockbox . The few necesary modifications for the DX90 port
was done by headwhacker form head-fi.org. Unfortunately i could not try out the final state of the DX90 port.
The port is hosted on android (without java) as standalone app. The official Firmware is required to run this port.
Ilia did modify the source files for the "android" target in the rockbox source to make the DX port work. The work I did
was to separate the code for DX50 (&DX90) from the android target.
On this Target Ilia used source from tinyalsa from AOSP. I did not touch that part of the code because I do not understand it.
What else I changed from Ilias sources besides the separation from the target "android":
* removed a dirty hack to keep backlight off
* changed value battery meter to voltage battery meter
* made all plugins compile (named target as "standalone") and added keymaps
* i added the graphics for the manual but did not do anything else for the manual yet
* minor optimizations
known bugs:
* timers are slowed donw when playback is active (tinyalsa related?)
* some minor bugs
Things to do:
* The main prolem will be how to install the app correctly. A guy called DOC2008 added a CWM (by androtab.info) to the
official firmware and Ilia made a CWM installation script and a dualboot selector (rbutils/ibassoboot, build with
ndk-build). We will have to find a way to install rockbox in a proper way without breaking any copyrights.
Maybe ADB is an option but it is not enable with OF by default. Patching the OF is probably the way to go.
* All the wiki and manual
to build:
needed: android ndk installed, android sdk installed with additional build-tools 19.1.0 installed
./tools/configure
select iBasso DX50 or iBasso DX90
make -j apk
the content of rockbox.zip/.rockbox needs to be copied to /system/rockbox/app_rockbox/rockbox/ (rockbox app not needed)
the content of libs/armeabi to /system/rockbox/lib/ (rockbox app needed)
The boot selector is needed as /system/bin/MangoPlayer and the iBasso app as /system/bin/MangoPlayer_original. There
is also the "vold" file. The one from OF does not work with DX50 rockbox (DX90 works!?), the one from Ilia is necessary.
Until we have found a proper way to install it, it can only be installed following the instructions of Ilia on his
bitbucket page, using the CWM-OF and his installation script package.

With LCD driver all calculation will be performed on RGB888 and the hardware/OS
can display from our 24bit framebuffer.
It is not yet as performance optimized as the existing drivers but should be
good enough.The vast number of small changes is due to the fact that
fb_data can be a struct type now, while most of the code expected a scalar type.
lcd-as-memframe ASM code does not work with 24bit currently so the with 24bit
it enforces the generic C code.
All plugins are ported over. Except for rockpaint. It uses so much memory that
it wouldnt fit into the 512k plugin buffer anymore (patches welcome).

Although both players basically have the same keys, the
differences in the layout is rather big, so I think both
deserve their own keymaps.
(On the yh820 the FFWD/PLAY/REW buttons are located above the
direction keys, on the yh920 at the side of the player.
Furthermore the yh920/925 has a REC switch, whereas
yh820 has a push button.)

This patch completes the plugin keymaps for the Zen X-Fi3 and enables those plugins for compilation.
One key was changed in "button-target.h" for compatibility with Rockboy.
This also caused the changes to "keymap-zenxfi3.c", to keep the stock functionality (no further changes in here).

The "plot" variable was left NULL when FFT_FREQ_SCALE key wasn't defined.
Please add FFT_FREQ_SCALE keys to targets missing them! I added the key
for Clip Zip and reminders for others.

Helps appearance especially with the spectrogram view since it no longer
must be scrolled out of the way to avoid artifacts.
Additionally, allow settings to be saved and clean up some misellaneous
stuff to help graphics performance.
Still other "pointless" work to do on it... :-)

Additional status callback is added to pcm_play/rec_data instead of
using a special function to set it. Status includes DMA error
reporting to the status callback. Playback and recording callback
become more alike except playback uses "const void **addr" (because
the data should not be altered) and recording uses "void **addr".
"const" is put in place throughout where appropriate.
Most changes are fairly trivial. One that should be checked in
particular because it isn't so much is telechips, if anyone cares to
bother. PP5002 is not so trivial either but that tested as working.

This port is a hybrid native/RaaA port. It runs on a embedded linux system,
but is the only application. It therefore can implement lots of stuff that
native targets also implement, while leveraging the underlying linux kernel.
The port is quite advanced. User interface, audio playback, plugins work
mostly fine. Missing is e.g. power mangement and USB (see SamsungYPR0 wiki page).
Included in utils/ypr0tools are scripts and programs required to generate
a patched firmware. The patched firmware has the rootfs modified to load
Rockbox. It includes a early/safe USB mode.
This port needs a new toolchain, one that includes glibc headers and libraries.
rockboxdev.sh can generate it, but e.g. codesourcey and distro packages may
also work.
Most of the initial effort is done by Lorenzo Miori and others (on ABI),
including reverse engineering and patching of the original firmware,
initial drivers, and more. Big thanks to you.

Also fix some errors in pluginlib_actions.c which
were causing the SA9200 build to crap out when
building plugins, and also disable plugins for the
SA9200 in the configure script (no idea why they

It handles exit() properly, calling the handler also when the plugin returns
normally (also make exit() more standard compliant while at it).
It also holds PLUGIN_HEADER, so that it doesn't need to be in each plugin anymore.
To work better together with callbacks passed to rb->default_event_handler_ex() introduce exit_on_usb() which will call the exit handler before showing the usb screen and exit() after it.
In most cases rb->default_event_handler_ex() was passed a callback which was manually called at all other return points. This can now be done via atexit().
In future plugin_crt0.c could also handle clearing bss, initializing iram and more.
