Lorenzo Miori Samsung YP-R1: fix OF boot shortcut 9y ago

Initial commit of the Samsung YP-R0 port. 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. Flyspray: FS#12348 Author: Lorenzo Miori, myself Merry christmas to ypr0 owners! :) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31415 a1c6a512-1295-4272-9138-f99709370657

Samsung YP-R0: remove deprecated kernel module This patch removes the deprecated kernel module to manage the fm-radio chip on the ypr0 target. http://gerrit.rockbox.org/r/#/c/1594/ implements the interface to the i2c bus by using the i2c-dev kernel driver, no need for additional complexity.

Samsung YP-R0/YP-R1 Safe Mode improvement 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. Change-Id: Id70541541fcfaa1234328485fab0696a3bd491c9

patch-firmware.sh

samsung ypr0: Include getty service in the patched firmware for usb serial shell access. 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.

README

To generate a firmware, run (paths may differ):

$ make
$ ./fwdecrypt R0.ROM <optional: destination path>
$ sudo ./patch-firmware.sh files . # needs sudo
$ ./fwcrypt R0.ROM <optional: source path>

After that, R0.ROM is patched and can load Rockbox.

rockbox.sh is a script to put into rockbox.zip. It's a small loader script
that sets stuff up.

files/lib/modules/si4709.ko is a replacement kernel module for fm radio support,
its source code is packaged in ./si4709.7z.
