Jz4740 is a multimedia application processor targeting for mobile
devices like e-Dictionary, eBook, portable media player (PMP) and
GPS navigator. Jz4740 is powered by Ingenic 360 MHz XBurst CPU core
(JzRISC), in which RISC/SIMD/DSP hybrid instruction set architecture
provides high integration, high performance and low power consumption.
JzRISC incorporated in Jz4740 is the advanced and power-efficient
32-bit RISC core, compatible with MIPS32, with 16K I-Cache and 16K
D-Cache, and can operate at speeds up to 400 MHz.
On-chip modules such as LCD controller, embedded audio codec, multi-
channel SAR-ADC, AC97/I2S controller and camera I/F offer a rich
suite of peripherals for multimedia application. NAND controller
(SLC/MLC), USB (host 1.1 and device 2.0), UART, I2C, SPI, etc. are
also available.
For more info about Ingenic XBurst Jz4740:

This patch introduces XBurst CPU support in U-Boot. It's compatible
with MIPS32, but requires a bit different cache maintenance, timer
routines, and boot mechanism using USB boot tool, so XBurst support
can go into a separate new home, cpu/xburst/.

Changes since v7:
* Fix checkpatch errors/warnings
Changes since v6:
* Rebased against the latest U-Boot/MIPS codebase (the previous patches
up to v6 were based on v1.1.6). $gp usage, relocation code and so on
are getting synced with the current MIPS support in U-Boot.
* Use -mach=mips32, pass -EL specifiers in PLATFORM_CPPFLAGS and
PLATFORM_LDFLAGS. This port works in Little-endian.
* Remove NAND-boot stuff. Those bits will be submitted as a nand_spl
support, once this Jz4740 base support is merged.
* jzsoc_init() is removed. calc_clocks() and rtc_init() will be
called through board_early_init_f().
* jz_serial.c is almost the same with standard ns16550 driver, but
we dont' use it, because it need a special tweak for jz4740 like
this:

serial_out(baud_divisor & 0xff, &com_port->dll);
serial_out((baud_divisor >> 8) & 0xff, &com_port->dlm);
If this is acceptable, we'll change to use standard ns16550 later.
* Coding styles and build warnings fixed

Jz4740 NAND flash controller can support:
* MLC NAND as well as SLC NAND
* all 8-bit/16-bit NAND flash devices
* HAMMING and RS hardware ECC
* automatic boot up from NAND flash devices
nand_ecclayout is set up for 2GiB NAND chip mounted in Qi LB60.
We'll bring up boot-from-NAND support in nand_spl/ in the future.

Changes since v7:
* Fix checkpatch errors/warnings
Changes since v6:
* Remove NAND-boot stuff. Those bits will be submitted as a nand-spl
support once this Jz4740 base support is merged.
* All previous comments from Scott are fixed.
* Bunch of coding style issues fixed.

Add support for the qi_lb60 (a.k.a QI Ben NanoNote) clamshell device
from Qi hardware:
http://en.qi-hardware.com/wiki/Ben_NanoNote
http://en.qi-hardware.com/wiki/Main_Page
http://en.wikipedia.org/wiki/Qi_hardware
This Jz4740-based clamshell device does not use NOR flash to boot.
The initial bring-up assumes that U-Boot is directly loaded into SDRAM
using USB boot tool, and starts from 0x80100000.
About USB boot tool
-------------------
Jz4740 is one of the XBurst processors with USB boot functionality
supported. The CPU can boot from a small ROM in the LSI, initialize
CPU and USB module, then wait for USB commands from the USB host.
We can send 8 KB binary data to the CPU cache using USB boot tool.
USB boot tool is available to the public at Ingenic website. Also
there is an alternative Debian package named xburst-tools.
