This is the basic port to the new target Samsung
YP-R1, which runs on a similar platform as YP-R0.
Port is usable, although there are still
some optimizations that have to be done.

The getty service mointors /dev/ttyGS0 (also created by the patched firmware).
When the g_serial.ko module is loaded this automatically enables shell access
via usb. It exposes a cdc-acm device to the host which is compatible to linux
(usb_serial.ko) and windows.
The g_serial.ko is not included module can be build from the YP-R0 open source
package provided by samsung. It can be loaded via rc.user on the internal memory.

This is an improvement for the special
mode present in the samsung ypr0 target.
Apart adding new useful functionalities, it
fixes a random disconnection bug, solved by debouncing
and fully support to YP-R1 target.
This opens also the possibility to interface
this operating mode to rockbox USB functionality.

fixed a bug concerning bytes padding, since it wasn't correctly
implemented regarding original firmware structure.
This fixes ROM generation especially for ypr1.

They have been rewritten for being completely free and
as fast as possible.
Successfully extracted, patched, repacked and flashed
original firmware (tested on device and it worked)

To support fm radio a kernel module was written. This module is added to
the patched firmware that loads Rockbox. It's pre-compiled but its source
archive provided.
The kernel module provides raw-access to the built-in si4709 radio chip.
Our existing si 47xx drivers can be re-used this way.
The module itself was written Lorenzo Miori, I only integrated it
into the tree.

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.

Merry christmas to ypr0 owners! :)
