+The portable game console has
+@li Ingenic JZ4755 SoC;
+@li 64 MiB SDRAM;
+@li 4 GiB microSDHC card / 4 GiB NAND type Flash Memory;
+@li RS232 serial interface (LV-TTL levels on the board!);
+@li LCD display (480x272);
+@li Video out interface;
+@li 1xUSB interface;
+@li buttons.
+
+The game console uses U-Boot 1.1.6 as bootloader.
+
+barebox-rzx50 mini-howto:
+
+1. Connect to the game console's UART (see. http://a320.emulate.su/2012/01/19/uart-na-ritmix-rzx-50/);
+
+2. Unblock U-Boot console (see. http://a320.emulate.su/2012/01/25/rzx-50-dostup-k-konsoli-u-boot/); Please note that U-Boot's Zmodem support does not work;
+
+3. Boot Ritmix linux and login;
+
+4. Upload barebox.bin via Zmodem
+@verbatim
+ # cd /tmp
+ # rz
+@endverbatim
+
+5. Write barebox to onboard flash
+@verbatim
+ # dd if=barebox.bin of=/dev/mmcblk0 seek=1048576 bs=1 count=262144
+@endverbatim
+
+6. Reboot RZX-50, next in U-Boot console start barebox:
+@verbatim
+ CETUS # msc read 0xa0800000 0x100000 0x40000; g a0800000
+@endverbatim

I read the patches, applied them and then I saw this sentence ;)
However, the patches look good and are not touching unrelated stuff, so
it should be fine.
