6c7c946cad common: Convert the U-Boot commands to LG-arrays
This patch converts the old method of creating a list of command
onto the new LG-arrays code. The old u_boot_cmd section is converted
to new u_boot_list_cmd subsection and LG-array macros used as needed.

Minor adjustments had to be made to the common code to work with the
LG-array macros, mostly the fixup_cmdtable() calls are now passed the
ll_entry_start and ll_entry_count instead of linker-generated symbols.

The command.c had to be adjusted as well so it would use the newly
introduced LG-array API instead of directly using linker-generated
symbols.

80421fcc3e MIPS: Ingenic XBurst Jz4740 processor support
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:
  http://en.ingenic.cn/eng/
  http://www.linux-mips.org/wiki/Ingenic

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/.

9558b48af0 console: Implement pre-console buffer
Allow redirection of console output prior to console initialisation to a
temporary buffer.

To enable this functionality, the board (or arch) must define:
 - CONFIG_PRE_CONSOLE_BUFFER - Enable pre-console buffer
 - CONFIG_PRE_CON_BUF_ADDR - Base address of pre-console buffer
 - CONFIG_PRE_CON_BUF_SZ - Size of pre-console buffer (in bytes)

The pre-console buffer will buffer the last CONFIG_PRE_CON_BUF_SZ bytes
Any earlier characters are silently dropped.

68cebb8027 MIPS: Move timer code to arch/mips/cpu/$(CPU)/
Current timer routines (arch/mips/lib/timer.c) are implemented assuming
that MIPS32 coprocessor (CP0) resources, Counter and Compare registers
in this case, are available.  But this doesn't always work.

We need to make sure that all MIPS-based systems don't necessarily use
CP0 counter/compare registers as time keeping resources.  And some MIPS
variant processors might come with different hardware specs with genuine
MIPS32 CP0 registers.

With this change, each $(CPU)/ directory can have its own timer code.

660da0947a MIPS: Introduce --gc-sections for MIPS
All architectures but MIPS are using --gc-sections on final linking.
This patch introduces that feature for MIPS to reduce the memory and
flash footprint.

7aa1f198c8 MIPS: Coding style cleanups on common assembly files
Fix style issues and alignments globally.  No logical changes.
- Replace C comments with AS line comments where possible
- Use ifndef where possible, rather than if !defined for simplicity
- An instruction executed in a delay slot is now indicated by a leading
  space, not by C comment
