/** @page rzx50 Ritmix RZX-50 game console
Ritmix RZX-50 is a portable game console for the Russian market.
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
