[PATCH v3 0/8] MIPS: improve Ingenic JZ4755 device tree support

[PATCH v3 0/8] MIPS: improve Ingenic JZ4755 device tree support

[Antony Pavlov]

This patcheseries moves Ingenic JZ4755 UART initialization
into device tree and makes JZ4755 device tree organization
more clear.

This patchseries is a part of work on Ingenic chips support
and prepares MIPS board support switch to device tree.
Next patchseries will add device tree Ingenic gpio, clk
and pinctls support.

Changes since v2:
  * add the plat pointer check into "make FCR setup value part of struct ns16550_priv"
  * add the "serial: ns16550: add compatible entry for "ns16450"" commit
  * rebase over updated next branch

Changes since v1:
  * use "make FCR setup value part of struct ns16550_priv"
    instead of "make it possible to get reg_write() from devtype";
  * add a trivial "fix whitespaces" patch.

[PATCH v3 8/8] MIPS: boards: rename rzx50 -> ritmix-rzx50

[Antony Pavlov]

All MIPS board use <vendor>-<model> name template save Ritmix RZX-50.
This commit fixes this inconsistency.

+/** @page ritmix-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
